Small pizza

Diameter = 15 cm
Medium pizza
Diameter = 30 cm

I$ a medium pizza twice as large as a small pizza?
Use calculations to support your answer.
A medium
plz can someone help me

nope , four times

area = pi r^2
NOT pi r

(2r)^2 = 4 r^2

Yes, I can definitely help you with that question.

To determine if a medium pizza is twice as large as a small pizza, we need to compare their sizes based on their diameters.

The area of a circle is calculated using the formula A = πr^2, where A represents the area and r represents the radius of the circle.

Given that the diameter of the small pizza is 15 cm, we can calculate the radius by dividing the diameter by 2: r = 15 cm / 2 = 7.5 cm.

Now let's calculate the area of the small pizza using the formula:
A_small = π * (7.5 cm)^2

To calculate the area of the medium pizza, we repeat the same process. The diameter of the medium pizza is given as 30 cm, so its radius would be: r = 30 cm / 2 = 15 cm.

Now let's calculate the area of the medium pizza:
A_medium = π * (15 cm)^2

To determine if the medium pizza is twice as large as the small pizza, we can compare their areas. If A_medium is exactly twice as large as A_small, then the medium pizza is twice the size of the small pizza.

Now, let's calculate the areas:

A_small = π * (7.5 cm)^2
= 3.14 * (7.5 cm)^2
≈ 176.71 cm^2

A_medium = π * (15 cm)^2
= 3.14 * (15 cm)^2
≈ 706.86 cm^2

Comparing the areas, we find that A_medium is approximately four times larger than A_small, not twice. Therefore, a medium pizza with a diameter of 30 cm is not twice as large as a small pizza with a diameter of 15 cm.

So, to answer your question, no, a medium pizza is not twice as large as a small pizza, based on their respective diameters and calculated areas.
