An extra-large pizza has a diameter of 18 inches and is cut into 12 equal pieces. find the length of the crust of 1 piece, rounded to the nearest hundredth.

The length of the crust of 1 piece is 4.72 inches.

Given that,

Based on the above information, the calculation is as follows:

We know that

Here PI should be 3.14

So,

Circumference be

= 56.52 inches

Now the length should be

= 4.71 inches

Therefore we can conclude that the length of the crust of 1 piece is 4.72 inches.

circumference of the pizza = PI*d

using 3.14 for PI

 circumference = 3.14*18 = 56.52 inches

 56.52 /12 = 4.71 inches of crust

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
