Asked:

Find the area of tambourine's surface.

Given:

Diameter —> 10inches

Pi —> 3.14

Plan:

As we already have the given diameter and the pi included, we need to find the radius of the diameter which is basically 5inches.

10÷2 = 5

Now, to get the area of the surface of the tambourine, we will need this formula;

A= (pi) r²

Solution:

A= 3.14(5²)

= 3.14 (25)

= 78.5 inches
