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

Hi there! The answer is 210 pages.

We can find our answer by looking at the proportions:
20 % is 42 pages.
10 % is 21 pages (42 / 2).
100% is 210 pages. (21 × 10).
