Textbook Problem

A spherical storage tank filled with water has a radius length of 10 ft. Use the calculator value of π to find to the nearest tenth of a unit the approximatea) surface area of the sphere.b) volume of the sphere.

To determine

a)

To find:

The approximate surface area of the sphere.

Explanation

Given:

A spherical storage tank filled with water has a radius of 10 ft.

Formula used:

The surface area of the sphere is S=4πr2.

Calculation:

We have r=10

Thus the surface area is

S=4πr2

To determine

b)

To find:

The approximate volume of the sphere.
