Question

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

Answer 1

Answer:

1.85 liters

Step-by-step explanation:

The formula of the volume of a cylinder is:

$\pi r^2h$

$\pi \times 2^2 \times 9$

$\pi \times 4 \times 9$

$36\pi$

$=113.097336$

To get in liters, divide the volume value by 61.024.

$113.10/61.024$

113.10 inches^3 is equal to 1.8533769 liters.

Answer 2

Answer:

About 113 in³.

Step-by-step explanation:

We need to find the volume of the vase.

The vase is a cylinder.

Volume of a cylinder is: $V=\pi r^2h$

We are given the height of 9 in and the radius of 2 in.

Using 3.14 for pi:

$3.14*2^2*9\\\\2^2=4\\\\3.14*4*9\\\\12.56*9\\\\\boxed{113.04}$

Mary should pour about 113 cubic inches into the vase.
