Question

If the difference between the circumference and the radius of a circle is 37cm ,∏=22/7, the

circumference (in cm) of the circle is​

Answer 1

Answer:

14

Step-by-step explanation:

Given the difference between circumference of circle and radius is 37 cm

Let the radius of circle is x cm

Then circumference of circle =2πr

∴2πr−r=37

⇒

7

44

r−r=37

⇒44r−7r=256

⇒37r=259

⇒r=7

So Diameter=2×7=14 cm

Answer 2

Answer = 44cm

Explanation

Let the radius be = "r"

Circumference = 2∏r

                         => 2 * 22/7 * r = 44r/7

Difference between cirumference and radius = 44r/7 - r = 37r/7

According to the given question,

37r/7 = 37

=> 37r = 37*7

=> r = 37*7/37

=>r = 7

Therefore, circumference:-

2∏r

=> 2 * 22/7 * 7

=> 44cm
