Question

A cone has a radius of 8 inches and a height of 12 inches.



What is the exact volume of the cone?



A.


32π in3


B.


96π in3


C.


256π in3


D.


768π in3

Answer 1

The formula for the volume of a cone is 1/3 * base area * height

Answer 2

\[\frac{ 1 }{ 3 }\times8^{2}\times \pi \times12\]

Answer 3

\[Volume of a \triangle is 1/3πr ^{2}h\]
1/3=0.33(π)(8)^2(12)=0.33(3.14)(64)(12)=795.85016
D is closest to the answer I got. 246(3.14)=803.84
