Find the area of the composite figure in terms of the figure (use 3.14 for pi)​
svp [43]

Answer:

105.12 ft²

Step-by-step 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\div2=25.12

Add 80 and 25.12:

80+25.12=105.12

Hope this helped!
