Find the area of a circle with a diameter of 20 inches. Use 3.14 for pi.

Solution:

Given, diameter of circle = 20 inches

We have to find the area of a circle.

Area of a circle = \(\Pi r^{2}\)

Where, r is the radius of the circle

Here, \(\Pi\) = 3.14

Radius = 20/2 = 10 inches

Area = \(\Pi(10)^{2}\)

= (3.14)(100)

= 314 square inches

Therefore, the area of the circle is 314 square inches.

Find the area of a circle with a diameter of 20 inches. Use 3.14 for pi.

Summary:

The area of a circle with a diameter of 20 inches (Use 3.14 for pi) is 314 square inches.
