Question

Find the circumference of the inner and the outer circles, shown in the given figure. (Take π= 3.14)​
​

Answer 1

Answer:

circumstance if the circle is2πr and solve the question to use this formula please

Answer 2

Answer:

Radius of the outer circle = 19 m

∴ Circumference of the outer circle = 2πr

= 2 × 3.14 × 19 = 3.14 × 38 m

= 119.32 m

Radius of the inner circle

= 19m – 9 m = 10 m  

∴ Circumference = 2πr = 2 × 3.14 × 9

= 56.52 m

Here the required circumferences are 56.52 m and 119.32 m.
