Question

Please answer question 31

Answer 1

Answer:

Circumference of a circle - Radius =37 cm...(Given)

We know that, Circumference of a circle =2πr (Where r = radius)

According to the statement:

2πr−r=37

2× 22/7  ×r−r=37

( 37/7  )r=37

∴r=7 cm

Therefore, circumference of a circle =2πr=2× 22/  7

= 44 cm
