The radius is 10 ft.

Explanation:

Given,

The volume (V) of the cone = 733 ft³

Height (h) = 7 ft

To find the radius (r) of the cone.

Formula

The volume of the cone is =
(1)/(3)πr²h

According to the problem,


(1)/(3)πr²h = 733

or,
(1)/(3)×
(22)/(7)×r²×7 = 733

or, r² =
(733X7X3)/(22X7)

or, r² = 99.9 = 100 (approx)

or, r =
√(100) = 10

Hence,

The radius is 10 ft.
