Question

Find the area of the shaded region

with full explanation please​

Answer 1

Answer:

88.05 cm2

Step-by-step explanation:

area of the circle = 22/7 r×r ( pi= 22/7 &diameter=15)

=22/7×7.5×7.5

=176.78

area of the unshaded part 1= 22/7×3.5×3.5=38.5cm2

area of the unshaded part2= 22/7×4×4= 50.24

So total area of the shaded part =176.78- (50.24+38.5)

= 88.05cm2
