User: Two sides of a triangle measure 18 meters and 11 meters. If the perimeter of the triangle is 37 meters, what is the length of the third side? 12 m 8 m 66 m 30 m

Weegy: P = 11 + 18 + x => x = 37- ( 11 +18) = 37 - 29 = 8 m , The length of the third side is 8 m

The circle circumference formula C = 2*Pi*r = 2*3.14*r = 81.64
r = 81.64/6.28 = 13 meters.
The radius of a circle that has a circumference of 81.64 meters is 13 meters.
