Question

Marsha likes to eat The cheese Chris edges of pizza. She ordered a large pizza that measured 18 inches across. If the cheese crust edge measures 3 inches from the edge of the pizza, what is the circumference of the rest of the pizza?

Answer 1

37.6991118431

Explanation:

Answer 2

Take the original diameter of 18 and subtract 3 twice from it since you have the crust on both sides to get 18-3-3=12. Now use 12 as your diameter and substitute into the formula for circumference which is C=pi*d. Now substitute the 12 in for d to get C = pi*12 inches or 12pi inches.
