Question

The radius of a cylinder is 15 cm, and its volume, found using 3.14 to approximate pi, is 19,782 cm^3.



What is the height of the cylinder?
____cm

Answer 1

Formula:

\(V = \pi r^2 h\)

Plug in what we know:

\(19782 = (3.14)(15^2)h\)

\(19782 = (3.14)(225)h\)

What's 225 * 3.14?

Answer 2

Is that the answer?

Answer 3

No, just multiply 225 * 3.14

Answer 4

\(225 \times 3.14\)

Answer 5

800.7

Answer 6

No, check again

Answer 7

706.5

Answer 8

Yes, now we divide: 19782 / 706.5

Answer 9

ok hold on

Answer 10

28?

Answer 11

Yes, that is our answer. So the height is 28.
