If the circumference of a circular sheet is 154 m, find its radius. Also, find the area of the sheet.

It is given in the question that,


Circumference of a circular sheet = 154 m


We know that,


Circumference of the circle = 2r


2 × × r = 154


Thus,




= 24.5 m


We know that,


Area of the circle = r2


Area =



= 22 × 85.75


= 1886.5 m2
