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?

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.

Step-by-step explanation:

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

5x+10 is the correct one

hope this
