Answer:

84.3034 m2

Step-by-step explanation:

The area of any regular polygon is given by the formula: Area = (a x p)/2, where a is the length of the apothem and p is the perimeter of the polygon. Plug the values of a and p in the formula and get the area. As an example, let's use a hexagon (6 sides) with a side (s) length of 10.

This right circular cone has a volume of 75π cubic inches. The height of the cone is 9 inches. What is the length of the radius?
sukhopar [10]
\bf \textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\quad 
\begin{cases}
r=radius\\
h=height\\
-----\\
V=75\pi \\
h=9
\end{cases}\implies 75\pi =\cfrac{\pi r^2\cdot 9}{3}\implies 75\pi =3\pi r^2
\\\\\\
\cfrac{75\pi }{3\pi }=r^2\implies 25=r^2\implies \sqrt{25}=r\implies 5=r
