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 = (1)/(2) \pi {r}^(2)`

So, this "quarter circle" is:

`a = (1)/(4) * (1)/(2) \pi {r}^(2)`

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

`a = (1)/(4) * (1)/(2) \pi * {8}^(2) \\ a = (1)/(8) \pi * 64 \\ \\ a = (64\pi)/(8) \\ a = 8\pi`

The area is 8π.

Answer 2

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
