I would try drawing the line on a coordinate plane to help.
The correct answer would be A. There is only a 1/8th percent chance of the spinner landing on 4.
80 * 70 percent = cookies sold
80 * .7 = cookies sold
56 = cookies sold
.0091 rounded to the nearest hundredths is .01.
C = πd ( in terms of the diameter ), C = 2πr ( in terms of the radius )
