Question

Find the circumference of the inner and outer circle radius of outer circle =19m and radius of inner circle=10m

Answer 1

Heya....

___________________

For, Inner Circle,

C = pi * diameter

C = 3.14 * 10 *2

C = 3.14*20

C = 62.8 cm

Hence, Inner Circumference is 63.8 cm

---------------------

Outer C = Pi* D

C = 3.14 * 19*2 

C = 3.14 * 38

C = 119.32 cm

Answer 2

hiii!!!

here's ur answer..

given radius of inner circle = 10m

circumference of inner circle = 2πr

= 2 × 22/7 × 10

= 440/7

= 62.85m ( approximately )

radius of outer circle = 19m

circumference of outer circle = 2πr

= 2 × 22/7 × 19

= 836/7

= 119.42m ( approximately )

hope this helps..!!
