Question

Find the area of the shaded region, given.
that:
Outer radius = 19 cm,
inner radius = 12 cm
pi
=22/7​

Answer 1

Answer:

640.86 cm^2

Step-by-step explanation:

Hey mate!! Here is your solution-

Solution-

Area of circle=(22/7 x r^2)

So,

Area of outer circle=(22/7 x 19^2) = 1134.57cm^2

Area of inner circle =(22/7) x 12^2) = 493.71cm^2

Area of shaded portion= Area of outer circle- Area of inner circle

= 1134.57 - 493.71

= 640.86 cm^2(Ans)
