To determine

To find:

The area of the circle.

Explanation

Given:

The circle whose diameter measures 20 cm and π3.14.

Theorem:

The area A of a circle whose radius has the length r is given by the formula, A=πr2.

From the given, the lengths of the diameter is 20 cm.

Here, r=10.

To find the area of the circle, substitute r=10 in A=πr2
