Question

The difference between the circumference and the radius of a circle is 37cm then find the circumference of the circle

Answer 1

Answer:

Step-by-step explanation:

Given that,

Circumference - radius of circle =37

2πr-r=37

=r(2π-1)=37

=r(2*22/7-1)=37

=r(44/7-1)=37

=r(37/7)=37

=r=37/37/7

=r=37*7/37

=r=7cm

Now,

Circumference (2πr) =2*22/7*7

=2*22=44cm

Hope this helps!!!!!

Answer 2

Answer:

44 cm2

Step-by-step explanation:

According to the question,

37 = Circumference ( C ) - Radius ( r )

37 = ( 2π - 1 ) r

37 = (2 x 22/7 - 1) x r

37 = (44 / 7 - 1) x r

37 = (37 / 7) x r

37 x 7 / 37= r

37 gets canceled in num and den

r = 7 cm

Now we have the radius to calculate the circumference ( C )

C =  2πr

C = 2 x 22/7 x 7

7 gets canceled in num and den

C = 2 X 22

C = 44 cm2
