Question

Nick has an empty cylindrical cup that he wants to fill with water, as shown below. He wants to fill the cup to the top. How much water, in cubical units, is needed to accomplish this task?


Select one:
A. 40π
B. 80π
C. 120π
D. 160π

Answer 1

Volume of a cylinder can be calculated like so: V = pi(r)^2 * h

Answer 2

\[\pi(r ^{2})h =V\]

Answer 3

r in this case is 4, and the height is 16. You got this.

Answer 4

0.36

Answer 5

V = pi(4^2)*16

What is 4^2?

Answer 6

4*4 = ?

Answer 7

16

Answer 8

And then 16*16 = ?

Answer 9

256

Answer 10

Hmm, it should come out to V = 256pi

Here is a picture of the volume of a Cylinder

Answer 11

Ohh, I said 16 sorry, the h = 10

So it's pi(4^2)*10 =V

Answer 12

4^2 = 16

And the h = 10

So it's V = 16*10pi

Answer 13

502.4????

Answer 14

Well, your answers are only given in terms of pi

If V = pi(r^2)h

And we know r and h.

r = 4
h = 10

Then we know it is \[\pi * 4^{2}*10 \rightarrow \pi * 16*10 \rightarrow \pi * 160 \]

Answer 15

16*10 = 160,

160pi

Answer 16
