Make a sketch to illustrate your answer.

**Reiny**, Tuesday, November 15, 2011 at 9:31pmArea of whole pizza = 100π , if by 10-inch pizza you mean a radius of 10

number of slices = 100π/15= 20.9 or 21 slices ?????

so the central angle of each slice = 360/21 = 17.1°

If the radius is 5 inches,

area = 25π

number of slices = 25π/15 = 5.2 ????

round off to 5 slices

angle at centre for each slice = 360/5.2 = 69

23°

Something tells me there is something wrong here.

Who cuts a pizza into 21 slices or 5 slices?
