Question

find the radii of the circle whose circumference are 242 CM
​

Answer 1

Answer:

Circumference of circle - 2πr

so,

242 = 2 ×22/7×r

11×7/2 = r

r = 38.5 cm

hope it will help you

Answer 2

Answer:

circumference of circle = 2pir

242= 2 ×22/7×r

242×7 /2×22 =r

11×7/2 = r

77/2 cm = radius

VERIFY

2pi r = 2×22/7×77/2 = 22×11 = 242
