Question

What is the volume of the frustum?

A. 503.77
B. 147
C. 588
D. 258.47

Answer 1

V = 1/3 πh(R^2 +r^2 + R*r)

V = 1/3 (3.14)(14) (4.2^2 + 2.5^2 + 4.2 * 2.5)

V = 1/3 (3.14)(14) (17.64 + 6.25 + 10.5)

V = 1/3 (3.14)(14) (34.39)

V = 503.93

Because i'm using π = 3.14

So answer is B. 503.77
