Question

The diameter of a pizza is 14 inches. The pizza has 8 slices of equal size. Which of the following is the closest to the area of a slice?

Answer 1

A full circle is 360 degrees, so one slice is an eighth of that. 360 / 8 = 45 degrees.

Answer 2

Explanation:

First let us find the area of the whole pizza. Area of a circle is:

`A=\pi r^2`

Then, we have diameter as:

`diameter/2=radius`

So, then using these formulas we would have,

`16/2=8\\A=8\pi \text{ or }25.12`

Now, one slice is
`(1)/(8)` of the entire pizza. So, we would have:

`8\pi/8=1\pi\\\text{ or }\\25.12/8=3.14`
