anonymous 4 years ago Which would be bigger , a 26 inch pizza or two 13 inch pizzas ? Or would they be the same?

1. anonymous

they are both the same

2. anonymous

so it would be equal

3. precal

use the area of a circle $A=\pi*r^2$

A 26 inch pizza is bigger.

5. anonymous

^^they are both the same

6. anonymous

They are not the same.

7. anonymous

$\frac{13^2\pi}{2*6.5^2\pi}$

8. anonymous

if u multiply 13 and 2 together u get 26

9. anonymous

Yes, but that's now how you solve it. You need to use a ratio of areas of circles.

10. anonymous

o so A=π∗r2

The 26in pizza is actually equivalent to 4 13 in pizzas.
