volume of cone = (1/3) * (π * radius2) * (height)

 

 

 

surface area of a cone \(= (π *\text{radius}*\text{slant height})+ (π * \text{radius}^2) \)

 

Or...if you are not given slant height:

 

surface area of a cone \(=\pi*\text{radius}(\sqrt{ \text{height}^2+\text{radius}^2}+\text{radius}) \)
