Answer: 45 meals.
Step-by-step explanation:
If she gives her dog 2/3 pounds of dog food for every meal, then we divide 30 by 2/3, because that's how many meals the dog will be able to eat out of 30 pounds.
30 divided by 2/3 is 45.
45 meals.

Volume of a Cone Formula: ![\displaystyle V = \frac{1}{3} \pi r^2h](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20r%5E2h)
- <em>r</em> is radius
- <em>h</em> is height
Step-by-step explanation:
<u>Step 1: Define</u>
Radius <em>r</em> = 12
Height <em>h</em> = 71
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cone Formula]:
![\displaystyle V = \frac{1}{3} \pi (12)^2(71)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20V%20%3D%20%5Cfrac%7B1%7D%7B3%7D%20%5Cpi%20%2812%29%5E2%2871%29)
- Evaluate exponents:
