# If the circumference of a circular sheet is 154 m, find its radius. Also, find the area of the sheet. (Take π = 22/7)

**Solution:**

Circumference of the circular sheet = 154 m

2πr = 154 m

2 × 22/7 × r = 154 m

r = 49/2 m = 24.5 m

Now, Area of circular sheet = πr^{2}

= 22/7 × 24.5 m × 24.5 m

= 1886.5 m^{2}

Thus, the radius and area of circular sheet are 24.5 m and 1886.5 m^{2} respectively.
