Question

Find the radius of a circle whose circumference is 308 sq. m.​

Answer 1

HI, HERE IS YOUR ANSWER:

circumference=308 sq. m

formula for circumference=2 x pi x r

2 x 22/7 x r=308

r=308 x7/44

radius = 49m

HOPE IT HELPS YOU!!

Answer 2

Circumference of Circle = 2πr

⇒ 308 m = 2πr

⇒ 308 m = 2 × π × r

⇒ 308 m = 2 × 22/7 × r

⇒ 308 m = 44/7 × r

⇒ 308 m × 7 = 44 × r

⇒ 308 m × 7 = 44r

⇒ 2156 m = 44r

⇒ 2156 m/44 = r

⇒ 49 m = r

⇒ r = 49 m

Note : The Circumference of circle cannot have square units
