Question

the circumference of a circle is 88cm.find the area of the circle ​

Answer 1

Circumference of Circle= 2πr

88 cm = 2 X 22/7 X r

88 X 7 / 2 X 22 = r

88 X 7 / 44 = r

2 X 7 = r

14 = r

So, Area of Circle= πr^2

= 22/7 X 14 X 14

= 22 X 2 X 14

= 616

Answer 2

Given,

The Circumference of a circle is 88 cm

To find,

The area of the circle

Solution,

The circumference of the circle = 2πr

So, 2 X 22/7 X r = 88

or, 44 /7 X r = 88

or, r = 88 X 7 / 44 = 14

Now, area of the circle = πr²

So, area = 22/7 X 14 X 14

Area = 44 X 14

Area = 616 sq cm

Hence, the area of the circle is 616 sq cm
