Question

A 7-in. pizza costs $8 and a 14-in. pizza costs $20. Tommy says the smaller pizza is a better buy because the larger pizza is twice as big and more than twice as expensive. Do you agree with his reasoning? If not, explain why not.​

Answer 1

Answer:

your answer is here !

Step-by-step explanation:

No, a pizza looks like a circle.

And we know that area of a circle depends on the radius.

Area of a circle = πr2, here pi (π) is constant.

So, we can clearly say that area of a circle is proportional to the square of the diameter.

Similarly, the cost a pizza depends on its area not its diameter.

follow me !

Answer 2

Step-by-step explanation:

pizza is in circular shape .

area of circle depends on radius

area of circle =pir r 2

here pie is constant.

therefore area of circle is directly proportional to square of diameter

so cost of pizza depends on area not on diameter.....
