Expert Answer
Given: Circumference of the circular sheet = 154 m
To find: Radius = ?, Area = ?
Solution:
Circumference of the circle = 2πr
2πr = 154 m
r = 154/2π
r = 154 × 7/2 × 22
r = 24.5 m
Now, the area of circular sheet = πr2
Area = (22/7)×/(24.5)2
Area = 1886.5m2
Thus, the radius and area of the circular sheet are 24.5 m and 1886.5 m2 respectively.
