Answer 3

Do you have an image attached to the problem?

Answer 5

To calculate the volume of a cylinder we need to know the radius of the circular cross-section of the cylinder - this is the measurement from the centre of the circle, to the outer-edge.

Answer 6

To get the radius we take the diamater and divide it by 2.

So 40/2 = 20 <-- That's our radius

Now we need to multiply that by the height 33mm

Answer 7

the height is 30 not 33

Answer 8

Okay, we're measuring in milimeters, correct?

So if I take 20mm and 30mm, then do the math, the answer comes out: 37714.28

Answer 9

the answers are
A.
37,680 mm3

B.
1256 mm3

C.
12,000 mm3

D.
150,720 mm3

Answer 10

One minute. Let me recheck my math

Answer 11

[Please wait... Verifyting answer...]

Answer 12

\[V = \pi r^2h\]

r = 20: \[20^2\] * 3.14 * 30

Answer 13

So find twenty=squard, then multiply it by pi and 30.

Answer 14

20 sqrt is 4.472135954999579

Answer 15

Volume = (pi)r^2h = (pi)(.5d)^2h

pi(20)^2(30)

12000(pi)

37699 mm^3
