Hi there!
Given,
Circumference of circle = 154 m
⇒ 2 π r = 154
⇒ r = 154 / 2 π
⇒ r = 154 x 7 / 2 x 22.
⇒ r = 49 / 2 = 24.5 m
∴ Radius of circle = 24.5 m
Now,
Area of circle A = π r²
A = π x 49 / 2 x 49 / 2 = 3773 / 2 = 1886.5 m²
Cheers!

Circumference of circle = 2 *22/7*r
2*22/7*r=154
R=154*7/22*2=49/2=24.5m
Area = pie r^2
22/7*24.5*24.5=1886.5m^2
Thanks......
2*22/7*r=154
R=154*7/22*2=49/2=24.5m
Area = pie r^2
22/7*24.5*24.5=1886.5m^2
Thanks......
