Suppose that x and y vary inversely, and x=30 when y=2. y equals 2. Find y when x=5.
Write a direct or inverse variation equation for each relation.

x 3 4 8
y 24 18 9

The number of people that can be fed by the 16 inch pizza is 4

The size of personal pizza = 8 inches

Hence, diameter of pizza = 8 inches

The area of the pizza can be calculated thus :

Area = π × 4² = 16π in²

Pizza for one person = 16π in²

The Larger pizza :

Area of larger pizza = π × 8² = 64π in²

Number of people who can eat the larger pizza :

Therefore, the larger pizza woukd feed 4 people
