Answer 3

and how can i answer my quetion 1 without a radius
pi(r^2)21=1000
can i find my radius from here, and then find the volume.?

Answer 4

yes, with no radius, it's difficult to find the volume. The problem has been garbled, apparently. Both the cylinder and the cone are incompletely specified.

And that doesn't even get into the bad grammar...
