Question

If the perimeter of a circle is 88 cm, find the area of a circle?​

Answer 1

Answer:

We know Circumference of a circle = 2πr

Where r is the radius of the circle

Circumference = 2πr (the value of π is 22/7)

88 = 2 × 22/7 × r

r = 88 × 7/44

r = 14 cms

The radius of the circle is 14 cms

We know Area of the circle = πr^2

Area = πr^2

Area of circle = 22/7 × 14 × 14

Area of circle = 22 × 2 × 14

Area of circle = 44 × 14

Area of circle = 616 cm^2

Answer the area of the circle is 616 cm^2
