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 ?

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

i do not know the answer i am sorry

i would have to say it is c.
