Question

If you were to a cut a 16 inch diameter pizza into 10 equal slices, what would be the area of each slice?

Answer 1

`A_("Slice")=20.11` `"in"^2`

Explanation:

.

The area of a circle is given by:

`A_("Circle")=pir^2` where `r` is the radius of the circle which is half the diameter.

`r=d/2=16/2=8` in

`A_("Pizza")=pi(8)^2=64pi`

`A_("Slice")=A_("Pizza")/10=(64pi)/10=6.4pi=6.4(3.14)=20.11` `"in"^2`
