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
