1. ## Find the Area of the shaded sector [Basic]

2. The area of the entire circle is $A=\pi r^2=16\pi$

$\displaystyle\frac{120}{360}=\frac{1}{3}$

The shaded area is 1/3 of the circle.

So you just simplify the fraction?

Just divide.

$\displaystyle\frac{16\pi}{3}$

1.04 .....
A little confused understanding this concept.
First how did you get it?( sorry for the annoying simple question)

$\displaystyle\frac{100}{2}$

Well 1/3 of $16\pi$ is $\displaystyle\frac{16\pi}{3}$

or 0.333333333?

10. That is 1/3.

$\displaystyle\frac{16\pi}{3}\approx 16.75516$

Oh now i get it
