Question

If the difference between the circumference and radius of a circle is 37 cm, then find the circumference of the circle. (Use π = 22/7).

Answer 1

SOLUTION:
Given:

Difference between the circumference and radius of a circle = 37 cm

Let r be the radius of the circle.

Circumference of a circle = 2πr

2πr - r = 37
2 ×(22/7) r - r = 37
44r/7 - r = 37
(44r - 7r)/7 = 37
37 r = 37 × 7
r = (37×7 ) / 37

r = 7 cm

Circumference of a circle = 2πr
= 2 ×( 22/7) × 7 = 44 cm

Hence, the Circumference of a circle is 44 cm.

Answer 2

Hey..!!!

___________

Solve:-

Let radius of the circle be r cm.

Then according to question,

2πr−r=37

=>r(2π−1)=37

=> r(44/ 7 −1)=37

r=37× 7/ 37=7cm

Circumference of the circle =2πr

=2×22 / 7 ×7=44cm Ans .
