Ameasuring wheel is used to calculate the length of a path. the diameter of the wheel is 8 inches. if the wheel rotates 15 times along the length of a path, how long is the path to the nearest foot?

To fint the length first one must find circumference to do that we use the formula D*Pi (diameter times Pi. Diameter = 8 Pi is the constant of 3.1415
so. 8*3.1415 = appox 25.1327. cow that we have  circumference we should multiply by the amount of times the wheel rotates (15)
so. 15*251327 = appox 376.9911in now convert to feet. 12 in = 1 foot so divide by 12
so 376.9911 / 12 = about 31.4
round down to 31 feet

For the first question the answer is a, for the second c, for the third d, for the 4th b, for the 5th a
