Final answer:
The volume of water the cone-shaped flower vase can hold, using the formula V = (1/3)πr^2h with 3.14 for π, a radius of 5 inches, and a height of 15 inches, is 392.5 cubic inches.
Step-by-step explanation:
To find the volume of water that a cone-shaped flower vase can hold, you use the formula for the volume of a cone, which is
. The given dimensions are a radius (r) of 5 inches and a height (h) of 15 inches. Using the value of 3.14 for
, the volume can be calculated as follows:


Therefore, the flower vase can hold 392.5 cubic inches of water.
