Question

HELPPPP!!! please!!!

Answer 1

By looking at the graph, we can see that the shape is a quarter of a circle.

The area of a circle is:

$a = \frac{1}{2} \pi {r}^{2}$

So, this "quarter circle" is:

$a = \frac{1}{4} \times \frac{1}{2} \pi {r}^{2}$

R is the radius (the diagram shows the radius is 8), so we can now find the area:

$a = \frac{1}{4} \times \frac{1}{2} \pi \times {8}^{2} \\ a = \frac{1}{8} \pi \times 64 \\ \\ a = \frac{64\pi}{8} \\ a = 8\pi$

The area is 8π.

Answer 2

Answer:

Step-by-step explanation:

r = 8 units

Area of the shape = 1/4 area of circle

=1/4 * πr²

= 1/4 * 3.14 * 8*8

= 3.14 * 2* 8

= 50.24 sq.units
