Question

find the radius of a circle whose circumference is 22cm and pie is22/7​

Answer 1

Answer:

2πr = 22cm --- 1

Now solve equation 1,

2 x 22/7 x r = 22

r = 22 x 7/22 x 2

(22 and 22 gets canceled and there's only 7 and 2 left)

r = 7 x 2

r = 14cm

Hope it helps~

Answer 2

Answer:

circumference of a circle = 2πr

Explanation:

given that - circumference of a circle=22cm

2x22/7xr=22

2r=22x7/22

2r=7

r=7/2

r = 3.5cm
