I have the equations for arc length and the sector area. I'm just a little confused on how to do it more easily. I also need help on finding the arc length and area when I already have the sector of the circle.
+128408 I don't understand what you mean when you say you have the "sector of the circle."
The sector area is given by pi * r^2 * (n / 360] where r is the radius and n is the measure (in degrees) of the central angle of the sector [the angle between the two radial lines of the sector]
The arc length is given by r [ n/180] *pi ....and r and n are as above
