FAQs
How do you find the area of a nonagon with the radius? To find the area of a nonagon (a polygon with 9 sides) with a radius, you can use the formula for the area of a regular nonagon:
Area = (9/4) * radius^2 * cot(π/9)
How do you find the area of a nonagon? The area of a nonagon can be found by dividing it into smaller triangles and then summing up the areas of those triangles. Assuming it’s a regular nonagon:
- Find the central angle of one of the triangles in the nonagon. For a regular nonagon, this angle is 360 degrees / 9 = 40 degrees.
- Calculate the area of one of those triangles using the formula: Area = (1/2) * base * height, where the base is the side of the nonagon and the height can be calculated using trigonometry (height = side / (2 * tan(40 degrees))).
- Multiply the area of one triangle by 9 to get the total area of the regular nonagon.
