Question

The volume of this cone is 602.88 cubic inches. What is the radius of this cone?

Use a = 3.14 and round your answer to the nearest hundredth.
9 in
r
inches

Answer 1

8

Explanation:

Volume of a cone formula: V =
`\pi r^(2) (h)/(3)`

where,

h is the height 9 in (assuming)

r is the radius want

v is the volume 602.88 cubic inches

`\pi` is a = 3.14

Plug in everything:

`602.88 = 3.14r^(2) ((9)/(3) )\\602.88 = 3.14r^(2) (3)\\1808.64 = 28.26r^(2)\\(1808.64)/(28.26) = (28.26r^(2))/(28.26) \\r^(2) = 64\\r = √(64) \\r = 8\\or\\r =-8`
