Question

Mary wants to fill a cylinder vase. At the flower store they told her that they should be filled 3/4 for the flowers to last the longest. Her cylinder vase has a radius of 2 inches and a height of 9 inches. How much water should marry pour into the vase?

Answer 1

Answer:

Find 3/4 of the height:

Height = 10 inches

3/4 of the height = 3/4 x 10 = 7.5 inches

Find the amount of water she should fill:

Volume = πr²h

Volume = π(4)²(7.5) = 377.14 in³

Answer: Mary should pour in 377.14 in³ of water.
