# math-PLEASE CHECK AND HELP

find the surface area and volume of the right circular cylinder. The radius is 3 and height 6.
This is what I put for volume:
v=pir^2h
pi(3cm)^2 6 cm=
54pi cm cubed
can you please check this and show work on how to do the surface area?
Thanks.

1. The volume of a cone is (1/3) pi r^2 h

You forgot the 1/3 factor in that formula.

The area of the side of a cone is
A = pi c^2*(r/c) = pi*r*c

where c is the slant height.

For the total cone area, you must add the bottom, pi r^2.
