Question

how do i find the area of the shaded region

Answer 1

Using the given info, find the area of the "slice of pie."
Next, find the area of the triangle.
Subtract that from the area of the "slice of pie."

Answer 2

so how would i find the area of the slice of pie?

Answer 3

You will need the formula
s = theta*r, where s is the area subtended by the angle, theta is the angle in radians, and r is radius.

Answer 4

If you want to use degrees instead, then convert radians to degrees. There are pi radians in 180 degrees.
The formula for the area using degrees would be:
s = (pi/180)*theta*r, where theta is in degrees.

Answer 5

Yes, that's true. But note that the "slice of pie" is exactly 1/4 of a whole pie. The radius of the pie is given; how would you find the area of the whole pie? of 1/4 of that pie? Have fun with pie and pi.
