So you know 50% means half right? So then do 32*2 and you get 64.
28 is the coefficient of x and 35 is the constant
If we have a circle with a radius of 3 we need to find the diameter of the circle. Remember radius is half of the diameter. So, the diameter is 6 units.
Use the circumference formula: C=3.14D
C=3.14(6)
C=18.84 units
