A circular plate has circumference 21.4 inches. What is the area of this plate? Use 3.14 for pi. The area of this plate is about nothing square inches.

Area of circular plate is 36.5 square inches

Step-by-step explanation:

The formula for determining the circumference of a circle is expressed as

Circumference = 2πr

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

From the information given,

Circumference of circular plate = 21.4 inches. Therefore

2 × 3.14 × r = 21.4

6.28r = 21.4

r = 21.4/6.28

r = 3.41 inches

The formula for determining the area of a circle is expressed as

Area = πr²

Area of circular plate = 3.14 × 3.41² = 36.5 square inches
