Question

find the area of a circle whose circumference is 176cm

Answer 1

Hello
Here is ur answer.....

Given :  Circumference of Circle =176 cm

 Circumference of Circle = 2 πr
=> 2*22/7 *r =176
r =  176*7/44 = 28cm
Thus the radius of circle = 28cm

Area= πr^2
=22/7×28
=22×4
=88 cm^3

Answer 2

$2\pi r \: = 176cm \\ 2 \times \frac{22}{7} \times r = 176 \\ r = \frac{176 \times 7}{2 \times 22} \\ r = 28cm \\ \\ area = \pi {r}^{2} \\ = \frac{22}{7} \times 28 \\ = 22 \times 4 \\ = 88 {cm}^{2}$
This is the correct answer and hope it helps you.
