Textbook Problem

A pump moves water at a rate of 8 π  ft 3 per minute. How long will it take the pump to empty the tank in Exercise 15 ? (Answer to the nearest whole minute.)

To determine

To find:

The time taken by the pump to empty the tank.

Explanation

Given:

A spherical storage tank filled with water has a radius of 10 ft. A pump moves water at a rate of 8π ft3 per minute.

Formula used:

The volume of the sphere is V=43πr3.

Calculation:

We have r=10

Thus the volume is

V=43πr3=43π(10)3V=40003π ft3

The pump moves water at a rate of 8π ft3 per minute
