Problema Solution
The diameter of a pizza is 20 inches. The pizza has 12 slices of pizza. What is the area of each piece? Round to the nearest whole number
Answer provided by our tutors
we will assume the pizza is a circle with diameter d = 20 in and has 12 equal slices of pizza
the area of a circle with diameter d = 20 in is:
A = (d/2)^2 pi
A = (20/2)^2 pi
A = 100pi
let 'x' represent the area of each piece:
12x = 100 pi
pi = 3.14
12x = 100*3.14
by solving we find:
x = 26 in^2
