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

Answer:

Step-by-step 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:

$diameter\div2=radius$

So, then using these formulas we would have,

$16\div2=8\\A=8\pi \text{ or }25.12$

Now, one slice is $\frac{1}{8}$ of the entire pizza. So, we would have:

$8\pi\div8=1\pi\\\text{ or }\\25.12\div8=3.14$

HOPE THIS HELPS!!!!!!!!

Answer 2

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