Question

Find the circumference of a circle whose radius is 10 m.

Answer 1

Radius = 10 m
Circumference = 2πr
=> 2 × 22÷7 × 10
=> 44 × 10 ÷ 7
=> 440 ÷ 7
=> 62.86 m.

Answer 2

Hey dear!!
_____________________________________________________________________________________________________

Radius of the circle = 10m
∴Circumference of the circle = 2πr
                                              = 2 × 3.14 × 10 
                                              = 62.8m
