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 =
πr²h
According to the problem,
πr²h = 733
or,
×
×r²×7 = 733
or, r² =

or, r² = 99.9 = 100 (approx)
or, r =
= 10
Hence,
The radius is 10 ft.
