Formula to find the volume of the cone is:
Volume =![\pi r^2\frac{h}{3}](/tpl/images/0086/1572/9956f.png)
Where r = radius of the base of the cone
and h= height of the come.
Given, h = 8 and r = 5.
So, first step is to plug in these values in the above formula to get the volume. Therefore,
Volume =![\pi *5^2*\frac{8}{3}](/tpl/images/0086/1572/8a275.png)
= 3.14 * 25 * 2.66667 Since π = 3.14
= 209.4
Hence, the volume of cone is A: 209.4 ft³.
Hope this helps you!

one key difference is that in constructing a square, you have to construct a perpendicular bisector but when constructing a hexagon, you do not have to construct a perpendicular bisector. one similarity is that both constructions rely on the radius/diameter.
