Question

estimate the area of the top of a round Pizza that has a diameter of 16 in round to the nearest tenth

Answer 1

We will solve as follows:

*First: We calculate the radius of the pizza:

`r=(16)/(2)\Rightarrow r=8`

*Second: We will replace in the following expression:

`A=\pi r^2`

That is:

`A=\pi(8)^2\Rightarrow A=64\pi\Rightarrow A\approx201.1`

So, the area of the pizza is approximately 201.1 squared inches.
