Question

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

Answer 1

Answer:

8

Step-by-step explanation:

Volume of a cone formula: V = $\pi r^{2} \frac{h}{3}$

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:

$602.88 = 3.14r^{2} (\frac{9}{3} )\\602.88 = 3.14r^{2} (3)\\1808.64 = 28.26r^{2}\\\frac{1808.64}{28.26} = \frac{28.26r^{2}}{28.26} \\r^{2} = 64\\r = \sqrt{64} \\r = 8\\or\\r =-8$
