Question

the circumference of a circle is 176cm.find area of the circle?

Answer 1

circumference of circle = 176
2π r = 176
r = 176/2π
= 176× 7/44 = 28
Area of circle = π r^2 = 22/7× 28 × 28 =
22× 4×28 =2464

Answer 2

Hello friends...
Solution:-
We know that :
The circumference of the circle is= 2πr
(where r is the radius of. Circle)
Here
=> 2πr= 176
=> r = 176/2π = 88/π = 88×7/22
=> r = 28 cm

Now
we know that
the area of circle = πr²

=> πr² = 22/7 × 28² = 22/7×784
= 112 × 22 = 2464

Hence
Area of circle = 2464 cm²
