Question

would it make more sense to buy two 10 inch pizzas or one 20 inch pizza? Explain your answer in detail.

Answer 1

Answer:

one 20 inch pizza

Step-by-step explanation:

radius of one 10 inch pizza is 10/2 = 5

so area of one 10 inch pizza : $\pi$× $5^{2}$ = 25 $\pi$

there are 2 ; 10 inch pizza so 25 $\pi$⇒$50\pi$

however 20 inch pizza radius is 10

so

$10^{2}$×$\pi$ = 100$\pi$

Answer 2

I think buying two 10 inch pizzas would make more sense because you can get different topping on each. For example where I live a 10 inch pizza is 5 dollars and a 20 inch pizza is 18 dollars so 2 10 inch pizzas would cost less as well.


Hope this helps! :)
