Question

2. Find the area of the shaded region below if the diameter of the inner circle is 20 m and the diameter of the outer circle is 24 m.

Answer 1

Answer: hello friend :)

Step-by-step explanation: here's ur answer...

diameter of inner circle=20cm

therefore radius=20/2=10cm

diameter of outer circle=22cm

therefore radius=22/2=11cm

area of inner circle=πr²

=22/7×10×10

=2200/7cm²

area of outer circle=πr²

=22/7×11×11

=2662/7cm²

hence, area of the ring=2662-2200/7

=462/7

=66cm²

hope this helps...
