Answer:

Circumference of the circular sheet=154m

⇒2πr=154m

⇒r=

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
