Question

. The diameter of the inner circle is 3 m and that of the outer circle is 11 m. Find the area enclosed by two circles.​

Answer 1

Answer:

Diameter of inner circle = 3m

Radius of inner circle = 3/2

Area of circle = πr^2

= 22/7 × 3/2 ×3/2

= 99/14m^2

Diameter of outer circle = 11m

Radius of outer circle = 11/2

Area of outer circle =πr^2

= 22/7 ×11/2 × 11/2

1331/7 m^2

ARE OF AREA ENCLOSED BY TWO CIRCLE = 1331/14 - 99/ 14

= 1232/14

=88m square

I hope It is correct.

Thanks you sir
