Question 9 (5 points)

The volume of a cone is 3847 cm The height of the cone is 8 cm. What is the length of the radius of the cone? Enter your answer in the box.
​

Answer 1

r=21.424

Explanation:

Volume = (1/3) . π . r² . h

3847 = (1/3) . π . r² . 8

3847 = (8/3)πr²

r²= 3847/(8/3)π

r² = 459

r= √459 = 21.424
