Question

What's the area of the composite figure below ?

Answer 1

Answer:

31.13

Step-by-step explanation:

If you look carefully, you will find a semicircle and a triangle.

The total area is =

$\frac{\pi r^{2}}{2} + \frac{1}{2} \times base \times height$

• r = 4 - 0 = 4
• base = |-4-0 | = 4
• height = 14 - 9 = 5

So if we put the values:

$\frac{\pi \times 4^{2}}{2} + \frac{1}{2} \times 4 \times 3\\= 31.13$
