It’s a result of the mathematical process used to find the volume of a sphere.

**How do you find volume when given surface area?** To find the volume of a three-dimensional object when given its surface area, you would need additional information about the shape and dimensions of the object. Surface area alone is not sufficient to determine volume because different three-dimensional shapes with the same surface area can have different volumes. The specific method for finding volume would depend on the shape of the object.

Without the third dimension, you cannot find the volume.

**How do you find volume with circumference and diameter?** If you have the circumference (C) and diameter (D) of a circle, you can use these values to find the radius (r) of the circle. Then, you can use the radius to calculate the volume of a cylinder or other relevant shape. The formula to calculate the radius from the circumference is:

Radius (r) = C / (2π)

Once you have the radius, you can proceed to calculate the volume using the appropriate formula.

**How do you find volume with thickness?** The volume of an object with thickness can be calculated by multiplying the area of its cross-section by its thickness. The specific formula and shape used to calculate volume will depend on the geometry of the object.

**What is the volume of a hollow sphere with thickness?** The volume of a hollow sphere with thickness can be calculated by subtracting the volume of the smaller inner sphere (the void) from the volume of the larger outer sphere. The formula is:

Volume of Hollow Sphere = (4/3)π(R_outer^3 – R_inner^3)

Where:

- R_outer is the radius of the outer sphere.
- R_inner is the radius of the inner sphere (void).

**What is the formula for the surface area and volume of a hollow cylinder?** The surface area and volume of a hollow cylinder can be calculated as follows:

Surface Area of Hollow Cylinder = 2πh(R_outer + R_inner)

Where:

- R_outer is the outer radius.
- R_inner is the inner radius.
- h is the height or thickness of the cylinder.

**Do two cylinders have the same volume?** Two cylinders can have the same volume if their dimensions (radius and height) are the same. However, cylinders with different dimensions will have different volumes. Volume is determined by the dimensions of the object.

**Does a hollow sphere have the same volume as a solid sphere?** No, a hollow sphere does not have the same volume as a solid sphere. A hollow sphere has an empty space (void) inside it, which reduces its volume compared to a solid sphere with the same outer dimensions (outer radius). The volume of a hollow sphere is less than that of a solid sphere.

**What is the volume of the hollow cylinder if the outer diameter is 12 m, inner diameter is 10 m, and height of the cylinder is 42 m?** To find the volume of the hollow cylinder with an outer diameter of 12 m, inner diameter of 10 m, and height of 42 m, you can use the formula for the volume of a hollow cylinder:

Volume of Hollow Cylinder = πh(R_outer^2 – R_inner^2)

First, calculate the radii:

- Outer Radius (R_outer) = 12 m / 2 = 6 m
- Inner Radius (R_inner) = 10 m / 2 = 5 m

Now, plug these values into the formula:

Volume = π × 42 m × (6 m^2 – 5 m^2) Volume = π × 42 m × (36 m^2 – 25 m^2) Volume = π × 42 m × 11 m^2 Volume ≈ 16368π cubic meters

So, the volume of the hollow cylinder is approximately 16368π cubic meters.

**What is the rule of cylindrical shell?** The rule of cylindrical shells is a mathematical technique used in calculus to find the volume of a solid of revolution (a three-dimensional shape formed by rotating a two-dimensional curve about an axis). It involves integrating the volume of thin cylindrical shells that make up the solid.

The formula for finding the volume using cylindrical shells is:

Volume = 2π ∫(from a to b) [radius(x) × height(x)] dx

This formula is commonly used when you have a curve that you want to revolve around an axis, and it is particularly useful for finding volumes of shapes like cones, frustums, and other solids with rotational symmetry.

**Is the volume of a cylinder 3 times?** The volume of a cylinder is not “3 times” any particular value. The volume of a cylinder is calculated using the formula:

Volume = π × Radius^2 × Height

The result is a specific value that depends on the dimensions (radius and height) of the cylinder. The volume is not a fixed multiple of a certain number; it varies with the dimensions you input into the formula.

**How do you find the radius and volume of a cylinder?** To find the radius and volume of a cylinder, you need specific information about the cylinder’s dimensions. If you have the volume and height of the cylinder, you can rearrange the volume formula to find the radius:

Radius = √(Volume / (π × Height))

If you have the radius and height, you can use the standard formula to calculate the volume:

Volume = π × Radius^2 × Height

These formulas allow you to find the radius and volume of a cylinder when you know the other two parameters.

**How to calculate the volume of a circle?** A circle is a two-dimensional shape, and it does not have volume. Volume is a three-dimensional measurement and is only applicable to three-dimensional objects like cylinders, spheres, and boxes. Circles have area, not volume, and the formula to calculate the area of a circle is:

Area = π × Radius^2

**How do I calculate liquid volume?** To calculate the volume of a liquid, you need to know the shape and dimensions of the container in which the liquid is held. Once you have this information, you can use the appropriate formula for the shape of the container (e.g., cylinder, cube, sphere) to calculate the volume of the liquid.

**What is the formula for the cubic feet of a cylinder?** The formula for the cubic feet of a cylinder is the same as the formula for the volume of a cylinder:

Volume = π × Radius^2 × Height

To express the result in cubic feet, you would need to ensure that the radius and height are both in feet.

**How do you calculate gallons in a round container?** To calculate the gallons in a round container, you need to know the dimensions of the container in feet (or meters, etc.) and then use the following formula:

Gallons = (π × Radius^2 × Height) / 231

The factor of 231 is used to convert the volume in cubic feet to gallons, as there are approximately 231 cubic inches in a gallon.

**What is the volume of a cylinder inside a sphere?** The volume of a cylinder inside a sphere can vary depending on the dimensions of the cylinder and its position within the sphere. To calculate the volume, you would need to know the radius of the sphere, the radius of the cylinder, and the height of the cylinder within the sphere. Without these specific dimensions, it’s not possible to provide a precise volume calculation.
