Circumference = 154 cm.
2πr = 154
r= 154×7/2×22
r= 49/2
r= 24.5cm.
Radius = 24.5cm.
2πr = 154
r= 154×7/2×22
r= 49/2
r= 24.5cm.

circumference = 2 pi r
154 = 2 multiply 22 / 7 multiply r
r = 154 multiply 7 / 22 multiply 2
r = 24 . 5 cm
154 = 2 multiply 22 / 7 multiply r
r = 154 multiply 7 / 22 multiply 2
r = 24 . 5 cm
