A circular plate has circumference 24.5 inches. what is the area of this plate? use 3.14 for pi.

Given:

Circumference of a circular plate = 24.5 inches.

To FInd:

Area of the circular plate

Solution:

By the formula of circumference

Circumference of a circular plate = 2πr

Where 'r' = radius of the plate

24.5 = 2

r =  [Since π = 3.14]

r = 3.90 inches

We know the formula of a circular plate is,

Area =  πr²

Therefore, A = (3.14)(3.90)²

A = 47.79 square inches

Therefore, area of the circular plate is 47.79 inches.
