Question

which one will you choose in order to have more pizza-one 18 inch pizza or two 12 inch pizza

Answer 1

Answer:

two twelve inch pizzas.

Step-by-step explanation: Two 12 inch pizzas have in total twenty four inches.

Answer 2

Answer:

One 18 inch pizza.

Step-by-step explanation:

Area of a circle = $\pi r^2$

Radius of the 18 inch pizza will be 9 inches and radius of the 12 inch pizza will be 6 inches.

Let $r_1 = 9, r_2 = 6$

Area of one 18 inch pizza will be:

$\pi \times 9^2 = \pi \times 81 = 81\pi$ inches.

Area of two 12 inch pizzas wil be:

$2 \times \pi \times 6^2 = 2 \times \pi \times 36 = 72 \times \pi = 72\pi$ inches.

$81\pi > 72\pi$.

Thus, the 18 inch pizza will be chosen to have more pizza.
