We are tasked to solve for the measurement of the radius of a circle with center O. The given values are the AB=7 units and AO=8.9 units. To further understand the problem, see attached picture. It is a right triangle, we can use Pythagorean theorem in solving for radius such as the solution is shown below:
AO² = r² + AB²
8.9² = r² + 7²
r² = 8.9² - 7²
r= 5.5
The radius is 5.5 units.
AO² = r² + AB²
8.9² = r² + 7²
r² = 8.9² - 7²
r= 5.5
The radius is 5.5 units.

Answer:
- Unit price of a 2-liter bottle of soda:
- Unit price of a case of twelve 12 ounce cans:
- The better bargain is the case of 12 ounce cans.
Step-by-step explanation:
Let be "x" the unit price (price/ounce) of the soda in the 2-liter bottle and "y" the unit price (price/ounce) of the soda in the case of twelve 12 ounces cans.
According to the data provided in the exercise, you know that:
1. The 2-liter bottle of soda is equal to 67.6 ounces.
2. That bottle costs $1.89
Then, the unit price is:
3. There are 12 ounce cans in the case. Then the total ounces is:
4. It costs $2.99. So the unit price is:
Since:
The better bargain is the case of 12 ounce cans.
