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
$\pi r$

r =
(24.5)/(3.14 * 2) [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.
