Question

What is the volume of the cone?

A. 2876.7 yd3
B. 2787.64 yd3
C. 4258.44 yd3
D. 4625.36 yd3

Answer 1

Volume of a cone

V = 1/3 *pi* r^2 *h

we know the diameter d=22

the radius r = 1/2 d = 1/2 (22) = 11

substitute in

V = 1/3 * pi * 11^2 * 22

V = 1/3 * pi * 121 * 22

V = 2662/3 * pi

pi is approximately 3.14

V =2787.639882 yd^3

Rounding

V = 2787.64 yd^3
