The area of the slanted part gives you the curved surface area. Now multiply this by to get the mass. Its volume is found by using the formula and the converted height and radius.
What is the total surface area of a cone if its radius 4cm and height 3 cm.
Slant Height l r2h2 Volume of the Cone. The formula for the slant height of a cone is t equals startfraction s minus pi r squared over pi endfraction where s is surface area of the cone. So the base radius of the cone is 5 inch. This page examines the properties of a right circular cone.
