Hi ,
Let the radius of the circle = r
Perimeter ( P ) = 2πr ----( 1 )
Perimeter = 176 cm ----( 2 ) [ given ]
( 1 ) = ( 2 )
2πr = 176 cm
2 × ( 22/7 ) × r = 176
r = (176) × ( 7/22) × ( 1/2)
r = ( 176 × 7 × 1 ) / ( 22 × 2 )
After cancellation
r = 28 cm
Therefore,
Radius of the circle = r = 28cm
I hope this helps you.
