ANSWER FAST

Answer 1

Answer:

The difference in area of the two pizzas is 113.14 inch².

Step-by-step explanation:

Martin ordered a pizza with a 16 inch diameter and Ricky ordered a pizza with a 20 inch diameter.

We have to calculate the approximate difference in area of the two pizzas.

Ara of pizza ordered by Martin = $\pi r^{2}$

                                                  = $\pi (\frac{16}{2} )^{2} =\pi 8^{2} =64\pi$

Area of pizza ordered by Ricky = $\pi (\frac{20}{2})^{2} =\pi 10^{2} =100\pi$

Difference in area = $100\pi -64\pi$

                             = $(36\pi )$

                             = 113.14 inch²

The difference in area of the two pizzas is 113.14 inch².
