Question

A pizza has a diameter of 18 inches. What is the area of one slice if one slice has a central

angle of 60. Draw and label a circle to represent the pizza. Show the formula and solve. Give
your answer to the nearest tenth.
a) Draw the figure.
b) Calculate the radius
c) Calculate the total area.
d) Calculate the area of one sector.

Answer 1

Explanation:

number of slices = 360 / 60 = 6

radius = 18 / 2 = 9 in

pizza area = (pi / 4) * d^2

= (pi / 4) * 18^2 = 254.5 in^2

area of one slice = 254.5 / 6 = 42.4 in^2
