Question

*Find the area of the figure below. Use 3.14 for pi.

Area= square inches

Answer 1

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`
