A.) 25 m
B.) 20 m
C.) 49/2 m
D.) None of these
​

Answer 1

circumference of circle=2πr

154=2×22/7×r

154=44/7×r

154×7/44=r

14×7/4=r

98/4=r

49/2=r

please follow me

Answer 2

Step-by-step explanation:

circumference= 2πr

therefore, 2πr= 154m

2×22/7×r= 154

r=154×7/2×22

r=24.5m

Hope it helps :)
