Question 936139
a slice of pizza has a central angle of 75 degrees and a radius of 8 inches.  find the exact length of the crust of this piece of pie
.
circumference = 2(pi)r = 2(3.14)8 = 50.24 inches
.
assuming the "crust" is the outer edge of the pizza:
length of crust = 75/360 * circumference
length of crust = 75/360 * 50.24
length of crust = 10.47 inches
