Question

The volume of a cone is 62.8 cubic inches. The height of the cone is 15 inches. What is the radius of the cone, rounded to the nearest inch? Use π = 3.14.

2 inches
4 inches
8 inches
9 inches

Answer 1

i believe the answer is 2 inches

Answer 2

R = sqrt 3 * (V /( pi * h))

V = 62.8

pi = 3.14

h = 15

now we sub

R = sqrt 3 * (62.8 / (3.14 * 15)

R = sqrt 3 * (62.6 / 47.1)

R = sqrt 3 * 1.33

R = sqrt 3.99

R = 1.9 rounds to 2 inches <===
