Mary wants to fill in a cylinder vase. At the flower store they told her that the vase should be filled 3/4 for the flowers to last the longest. Her cylinder vase has a radius of 4 inches and a height of 10 inches. How much water should Mary pour into the vase?

Answer: 376.98192 mL

Step-by-step explanation:

We are going to use this equation.

V = π * r² * h

according to the question we have the value for r and h, if you replace the values into the equation we will get following product:

note: also keep in mind that value of π is 3.141516

V = π * r² * h

V = π * (4in) ² * (10in)

V = 502.64256 in³

after we can divide this value in 4 equals parts

then we get the following equation:

502.64256 in³ / 4 = 125.66064 in³

after that that you can multiply this value by 3 to get the 3 parts of the cylinder vase for example:

125.66064 in³ * 3 = 376.98192 in³

and this result is the volume of water that we have to pour into the vase
