Surface Area and Volume of a Right Circular Cone

If we revolve a right-angled triangle about one of its sides by taking other as its axis then the solid shape formed is known as a Right Circular Cone.

Curved surface area of a Right Circular Cone\mathrm{\pi rl=\pi r\sqrt{h^2+r^2}}
Total surface area of a Right Circular Cone\mathrm{\pi r^2+\pi rl=\pi r(r+l)}
The volume of Right Circular Cone\mathrm{\left(\dfrac{1}{3}\right)\pi r^2h}
 r = radius, h = height, l = slant height
