# The figure shows three semicircles. Find (I) the perimeter (ii) the area, of the shaded region

Blah blah blah is the way you answer someone who talks so much without any sense.

hey! how are you? my name is maria, 19 years old.   yesterday broke up with a guy, looking for casual sex.

1) 87.92 cm

2) 615.44cm

Step-by-step explanation:

Circumference (C) = 2πr = πd (d=2r)

Area (A) = πr²

Use π ≈ 3.14

1. Given that d=28cm, substitute the given value for diameter to the formula for circumference:

⇒ C = (3.14)(28) cm = 87.92cm

2. Given that d=28cm, substitute the given value of diameter to the formula for finding the radius:

⇒ r = (½)(28) cm = 14cm

Then substitute the value of radius to the formula for area:

⇒ A = (3.14)(14)² cm = (3.14)(196) cm = 615.44cm
