Number of pieces = 12
Radius of circle = 1 cm
We need to calculate the area of pizza
Using formula of area
Put the value into the formula
We need to calculate the area of circle
Using formula of area
Put the value into the formula
Now, we multiply the result by 12 because they are 12 salamis.
So. the area of salamis will be
We need to calculate the area of cheese
The total area of the pizza and subtract the area of the salamis
Put the value in to the formula
Hence, The area of cheese is 388π cm.
