Question

answer the 7th question ​

Answer 1

Answer:

Let r be the radius of circle.

Difference between circumference and radius of circle = 37 cm

Circumference of circle = 2πr

                                  = 2 x 22/7 x r =44/7 x r

Now,

Difference between circumference and radius of circle = 2r - r

37 = 44/7 x r - r

37 = r(44/7-1)

37 = r(44 - 7)/7

37 = 37 / 7 x r

37 x 7/37 = r

r = 7 cm

Now , Circumference of circle = 44/7 x r

                                                 = 44/7 x 7

                                                 = 44 cm . 

∴ Circumference of circle = 44 cm
