Question 544932: Find r when A=10m^2 and theta= 2 radians
Answer by KMST(5328) (Show Source): You can put this solution on YOUR website!
I understand that in this problem you are trying to find the radius of a pie, knowing that a 2-radian slice has an area of 10 square meters.
That is quite a large pizza! Or is it apple pie?
A whole circle of radius has an area equal to

and, taken as an angle, measures, in radians,
So the area of a 2-radian slice is

So if , then, in meters, ,
or approximately 3.16 meters.
