Pls : d mario’s pizzeria bakes olive pieces in the outer crust of its 20-inch (diameter) pizza. there is at least one olive piece per inch of crust. how many olive pieces will you get in one slice of pizza? assume the pizza is cut into eight slices.

To find the circumference you need to use 3.14 as pi and multiply it by the diameter which is 20 inches which the answer is 62.8 which would round to 63 so about 63 olives|
To find the area use the radius which is always half of the diameter and square it by multiplying itself by itself then multiply it by pi (3.14) which is so the answer for the area is 314 inches squared.
And the circumference is never squared just it’s unit, ( feet, inches, etc.).

3cm and 6 and 9 cm that a possibility of that question
