Find the volume of a sphere if the diameter has the length 12 cm. Use π ≈ 3.14 .

To determine

To find:

The volume of a sphere.

Explanation

Formula used:

Volume of sphere:

V=43πr3

Given:

The volume of a sphere of the diameter has the length 12 cm. Use π=3.14

Calculation:

The diameter of a sphere as shown in the above figure.

d=12 cm.

Then the radius of the sphere is,

r=d2=122=6

The radius of the sphere is r=6 cm.

We substitute the values r=6,π=3.14 in above formula,
