Answer: 21

Step-by-step explanation:

The radius is 10 ft.

Step-by-step 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 = [tex]\frac{1}{3}[/tex]πr²h

According to the problem,

[tex]\frac{1}{3}[/tex]πr²h = 733

or,  [tex]\frac{1}{3}[/tex]×[tex]\frac{22}{7}[/tex]×r²×7 = 733

or, r² = [tex]\frac{733X7X3}{22X7}[/tex]

or, r² = 99.9 = 100 (approx)

or, r = [tex]\sqrt{100}[/tex] = 10

Hence,

The radius is 10 ft.
