To solve this problem you would use the area. The formula is A=pi x radius^2. So radius is half of diameter and the diameter is 8 so r=4. So everything comes to 16pi. This is if the question says to leave your answer in terms of Pi. If it doesn't say anything it would be acceptable to leave your answer this way. But you can also use 3.14 as an approximation for Pi.

The surface of cheese needed is equal to the surface of the pizza, 50.24 cm^2.

How many square centimeters of cheese should we use?

This will be given by the area of the pizza.

The pizza is a circle of diameter equal to 8cm. Remember that for a circle of diameter D, the area is:

A = 3.14*(D/2)^2

Then for the pizza, the area is:

A = 3.14*(8cm/2)^2 = 50.24 cm^2

This means that we need to use 50.24 cm^2 of cheese.
