here.....
it is given that...
2pir=154 m
or..
2×22/7×r=154 m
or ..
r=154×7/22×2
r=24.5 m
and now area ...=pir*2
......or 22/7×24.5×24.5
....=1886.5 m*2
hope it helps...:D

Circumference = 154 cm
Find the radius:
Circumference = 2πr
2πr = 154
r = 154 ÷ 2π
r = 154 ÷ 2(22/7)
r = 154 ÷ 44/7
r = 154 x 7/44
r = 24.5 cm
Find the area:
Area = πr²
Area = 22/7 (24.5)²
Area = 1886.5 cm²
Answer: The area is 1886.5 cm²
