Answer:

(4,312)/3 cubic ft.

Explanation:

A spherical storage tank has a diameter of 14 ft

volume of a sphere =
$(4)/(3)\pi *r^3$

r is the radius of the sphere

Diameter = 14 ft

Radius = diameter /2 = 14/2 = 7 ft

volume of a sphere =
$(4)/(3)\pi *7^3$

WE use 22/7 for pi

(4)/(3)*(22)/(7)*7^3

(4312)/(3)

V = (π/6)d^3
Using π = 22/7 and d = 14 ft, the volume is
V = (22/7)/6*(14 ft)^3 = 4,312/3 ft^3

The 3rd selection is appropriate.
