Question

The volume of a cylinder is 980647-10-05-00-00_files/i0200000.jpg in3. The height of the cylinder is 20 in. What is the radius of the cylinder

Answer 1

the file you attached isn't going anywhere--so the height is 20, right? What's the volume of the cylinder?

Answer 2

\[V=πr2h\] You just need to plug 20 into h and the volume you're given into V and then solve for r.

Answer 3

An example:
\[V=πr2h\]
\[200=πr2(20)\]\[200=πr40\] then divide by 40\[5=πr\] then divide by π\[5/π=r\] so in this case, the radius would be about 1.6 units. But in your case, you need to substitute your Volume in for V. But this is the same process. Does that help?
