What is the approximate area of the shaded sector in the circle shown below

jeyben [28]

Answer: B

Step-by-step explanation:

The area of a circle is pi*radius^2. But only a diameter is given, so in order to find the radius, you must divide the diameter by 2:

3.6/2 = 1.8

Now, you can plug the radius, 1.8, into the equation pi*radius^2 ( $\pi r^{2}$ ):

$\pi (1.8)^2 = \pi(3.24)$ = about 10.18

Lastly, you must divide the area 10.18 by 2 because you are looking for only half the area.

10.18/2 = 5.09
