Question

PLEASE ANSWER!
The circumference of circle is 188.4cm.find the area of the circle.(π=3.14) *​​

Answer 1

Given :-

Circumference = 188.4 cm

π = 3.14

To Find - Area of the circle

For finding the area of circle, we need to first find the radius of the circle.

For that, we will take the formula of circumference :-

C = 2πr cm

188.4 = 2 × 3.14 × r cm

188.4 = 6.28 × r cm

r = 188.4 / 6.28 cm

r = 30 cm

Now, formula for area of circle :-

= πr² cm

= 3.14 × (30)² cm

= 3.14 × 900 cm

= 2826 cm

Hence, the area of the circle = 2826 cm
