Answer:

100.26

Explanation:

You would find the area of the semi circles on either side of the rectangle by plugging the diameter into the formula for the area of a circle. Then you would add that to the are of the rectangle.

This is what that would look like:

1. Divide 6 (the diameter) by 2 because
r=(1)/(2) d


r=(1)/(2) 6


r=3

2. plug into the formula
A=\pi r^(2)


A=\pi 3^(2)

3. square the 3


A=\pi 9

4. multiply 9 by 3.14 (pi)


A=28.26

This means the area of both the semi circles added together would equal 28.26

Then you would use the formula
A=lw to find the area of the rectangle

1. plug in the numbers given


A= 12 ·
6

2. solve


A=72

Then add the area of the semicircles to the area of the rectangle


A=28.26+72

to get the area of the entire figure:


A=100.26
