Question

The volume of a cone is 1004.8 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.) (1 point) Group of answer choices 64 32 8 4

Answer 1

r = 8 inches

Explanation:

`(1)/(3)\pi r^(2)h=1004.8\\\\(1)/(3)*3.14*r^(2)*15=1004.8\\\\3.14*r^(2)*5=1004.8\\\\r^(2)=(1004.8)/(3.14*5)\\\\r^(2)=64\\\\r=√(64)\\\\ r=8`
