The path of a rotating lawnmower blade has a diameter of 24 inches and a circumference of about 75 inches. On a smaller model of the lawnmower, the blade has a circumference of about 12.5 inches. What is the diameter of the model?
The circumference is C = 2 * pi * r to find the diameter of the model C/ pi = 2*r or rewritten to C/pi = d Plug in what is given and solve 12.5/3.14 = d the diameter of the model is approximately 3.98 inches or 4 inches
