My math teacher didn't explain it to us. We have to build a robot, and some parts of it are cones.
I can find the radius and the circumference.
Thank you in advance!

You need to know the radius of the base r and the height h. If you can measure the sloping side length L it will save work in the calculation.
Volume = (1/3)*pi*(r^2)*h
Area = pi*r^2 [base] + pi*r*L [curved side] with L sqrt(r^2 + h^2)

Area = pi*r^2 [base] + pi*r*L [curved side] with L sqrt(r^2 + h^2)

Hello! The formula for a cone is the (basearea (which is the radius x radius x pi) times hight)/3. Understand? Sorry I have a little bit of a problem writing formulas without a pen ;) I don't really understand what you mean by area but I would guess that you are talking about the cones "cover" and basearea put together? That would be basarea plus (pi x radius x side of the cone)
