Someone , it will be great if you do

We will get shaded area when we subtract rectangle area from semicircle area.

Rectangle area is   Ar=a*b=16*6= 96 cm∧2

Semicircle area is  Asc= (r∧2 pi)/2

First we must find radius.

We know that the center of the semicircle ( or circle) is in the middle of the longer side of the rectangle.

Now we can find radius with Pythagorean theorem

r= √8∧2+6∧2= √64+36 =√100= 10cm => r= 10 cm

Asc=(10∧2 * pi)/2 = 50 pi cm∧2  

Shaded area is Asc - Ar = 50pi - 96 = 2 (25pi-48) cm∧2

Good luck!!!

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
