Question

Find the area of the composite figure in terms of the figure (use 3.14 for pi)​

Answer 1

105.12 ft²

Explanation:

Let's first find the area of the rectangle.

`10\cdot8=80` ft², so the rectangle has an area of 80ft².

To find the area of the semi-circle, we find the area of a whole circle and divide by two.

The formula to find the area of a circle is
`\pi r^2`. The radius is 4, as the diameter is 8.

`3.14\cdot4^2`

`3.14\cdot16`

`50.24/2=25.12`

Add 80 and 25.12:

`80+25.12=105.12`

Hope this helped!
