Asemicircle is attached to the side of a rectangle as shown.

what is the best approximation for the area of this figure?

use 3.14 to approximate pi.

Step-by-step explanation:

we know that

The area of the figure is equal to the area of a rectangle plus the area of semicircle

Step 1

Find the area of the rectangle

The area of the rectangle is equal to

we have

substitute

Step 2

Find the area of semicircle

The area of semicircle is equal to

we have

substitute

Step 3

Find the area of the figure

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

the answer is 0052
