Question

A circular plate has circumference 24.5 inches. What is the area of this​ plate? Use 3.14 for pi.

Answer 1

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 = 2πr

r = $\frac{24.5}{3.14\times 2}$ [ 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.
