Final answer:
To fill ten 8-inch tea glasses, Sally needs approximately 22.4 fluid ounces of tea.
Step-by-step explanation:
To figure out how much tea Sally needs to fill ten 8-inch tea glasses, we need to know the volume of each glass. Assuming the glass is cylindrical, the volume can be calculated using the formula: V = πr^2h, where V is the volume, r is the radius, and h is the height. Since the radius is half the diameter and the diameter is 8 inches, the radius is 4 inches. Now, we can substitute the values into the formula: V = π(4^2)(8) = 128π cubic inches. To convert this to fluid ounces, we can use the conversion factor that 1 fluid ounce is equal to 1.805 cubic inches. Applying the conversion, we get: 128π / 1.805 ≈ 22.4 fluid ounces. Therefore, Sally needs approximately 22.4 fluid ounces of tea to fill ten 8-inch tea glasses.
