Question

A circular pizza that is 15 inches in diameter is cut into 4 equal slices. What is the area of one of those slices?

Answer 1

Answer: 44.18inch^2

Explanation:

First, find the area of the pizza.

`A=\pi r^2`

We do not have the radius, but we do have the diameter; and we know that the radius is diameter divided by 2.

`(d)/(2)=r\\(15)/(2)=r\\ 7.5=r`

Now plug this into the formula.

`A=\pi r^2\\A=(3.14) (7.5)^2`

`A=176.71inch^2`

If this pizza was cut into 4 equal slices, we can assume that the area is divided by 4.

`(A)/(4)=Area-of-one-slice`

`(176.71inch^2)/(4)=?`

`A/slice=44.18inch^2`
