7th grade question easy will fan and medal - http://gyazo.com/152babf039249477a97dae82fe7d8d56

Answer 1

Do you know the formula for the volume of a cylinder? @Adrian93334

Answer 2

no

Answer 3

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

Where \(r\) is the radius and \(h\) is the height.

Answer 4

In this case, the radius is 12.2, and the height is 9.

Answer 5

We can plug this into the formula:

\(V = (3.14)(12.2)^2(9)\)

Answer 6

And you know that pi is 3.14.

Answer 7

see @Adrian93334 thats what i got earlier

Answer 8

Simplify:

\(V = (3.14)(148.84)(9)\)

Multiply:

\(V = (467.3576)(9)\)

Multiply:

\(V = 4206.2184\)

Answer 9

thats not one of the answers lol

Answer 10

But it's correct..your lesson probably has a different formula for the volume of a cylinder..

Answer 11

so it's C

Answer 12

@satellite73

Answer 13
