Answer:

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
