Let’s get right to it — we’re here to calculate the surface area or volume of a right circular cone. As you might already know, in a right circular cone, the height goes from the cone’s vertex through the center of the circular base to form a right angle. Right circular cones are what we typically think of when we think of cones.
There are two right circular cone formulas to know: The formula for the volume of a cone is (𝛑r²h)/3. The formula for the surface area of a right circular cone is 𝛑rs+𝛑r². Let's look at them both in further detail.
