Answer:

The area of the shaded region is o.o2355 square m

Step-by-step explanation:

Given diameter of the circle is d= 20 cm

radius \:  = r =  \frac{d}{2 }  =  \frac{20}{2}  = 10 \: cm

So, radius = r = 10 cm = 0.1 m

area \: of \: circle \: is \: \pi \times  {r}^{2}

Given three-quarters of the circle is shaded.

Area of shaded region is

 \frac{3}{4}  \times \pi {r}^{2}

 =  \frac{3}{4} \pi {(0.1)}^{2}

We know ,

\pi = 3.14

  = \frac{3}{4}  \times 3.14 \times 0.1 \times 0.1

= 0.02355 square m

The area of the shaded region is 0.02355 square m.
