Find the Surface area and volume of a cone with a height(not slant height) of 12.5cm and a diameter of 7cm.
How do I show work for this?
you show work by showing what you do to solve the problem. To start with,
a = πr(r+s) -- and recall from your previous post that s^2 = r^2+h^2
v = 1/3 πr^2 h
now just plug in your numbers. I assume you know that r is 1/2 the diameter ...
