Question

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

Answer 1

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! :)

Answer 2

one 20 inch pizza

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`
