Answer:
Circumference of the circular sheet=154m
⇒2πr=154m
⇒r=
2π
154
⇒r=
2×22
154×7
=24.5m
Now, Area of circular sheet=πr
2
=
7
22
×24.5×24.5
=22×3.5×24.5=1886.5m
2
.
Thus, the radius and area of circular sheet are 24.5m and 1886.5m
2
respectively.

SOLUTION:
circumference of circle =2πr = 154m
2 × 22/7 × r = 154
r = 154 × 7 /2 × 22
r = 49/2 m or 24.5 m
now,
area of circle = πr^2
22/7 × 49/2 × 49/2
3773/2 m or 1886.5 m
ANSWER : 1886.5 m
