Answer 2

Given

• C = 2π r.
• r = 5.

To Find

• Value C in C = 2π r.

Solution

C = 2π r

=> C = 2 × 22/7 × 5

=> C = 220/7.

Therefore, value of C is 220/7.

Verification

Let's verify our answer by finding the value of r.

220/7 = 2 × 22/7 × r

=> 220/7 = 44/7 r

=> r = (220/7) × (7/44)

=> r = 5.

Hence, verified.
