Question

In the given figure, find the area of the shaded portion if
AC = 54 cm, BC = 10 cm, O is the centre of bigger
circle.​

Answer 1

Answer:

subtract the area of inner circle from area of outer circle

Step-by-step explanation:

area of outer circle radius = half of

AC = 28

area = pi r^2 = 22/7*27*27 = 2291

for inner circle radius = OB

OB = OC - BC = 27-10=17

area = pi r^2 = 22/7*17*17=908

area of shaded portion = 2291-908

= 1383(approx)
