A candle in the shape of a circular cone has a base of radius r and a height of h that is the same length as the radius. Which expresses the ratio of the volume of the candle to its surface area(including the base)? For cone, V=1/3pir^2h and SA=pir^2+pir sqrt r^2 +h^2.
Think that's how you type it. Possible answers;
3r-sqrt h^2+r^2/8r-h
r(1- sqrt 2)/-3
rh/3r+ sqrt h^2+r^2
r/3+sqrt 2
Could someone please help me with this problem?
