Alex Ar [27]

Answer:

About 376.99 cubic inches

Step-by-step explanation:

Cylinder has a volume of:

V=\pi r^2h

Where

V is the volume

r is the radius

h is the height

We need to find the volume of the cylinder, then multiply that answer by 3/4 to get the solution to this problem. First, the full volume of the cylinder.

Given

r = 4

h = 10

So,

V=\pi r^2h\\V=\pi (4)^2 (10)\\V=502.65

Now, we multiply by 3/4:

502.65*\frac{3}{4}=376.99

Mary should be vase to 376.99 cubic inches
