Question

how do u find the area of a sector?

Answer 1

What shape is the sector? triangular. rectangular. square? cube?

Answer 2

it is a circle with like 1/4 shaded wiht one side says 2 and is a90 degrree angel

Answer 3

the formula for the are of a circle is
\[A={\Pi}r^2\]

Answer 4

you find the proportion of the total area by finding the angle ratio. Let a be the angle of the shaded area.
Then the fraction of the total area that is shaded is a/360.

So the area of the shaded region is

\[(a/360)*\pi r^{2}\]

in your case a=90
90/360=1/4
r=2 ( i think this is what you mean by a side saying 2)
\[A=(1/4)\pi 2^{2}=\pi\]
