The video describes the "Calculation of the surface area of the cone without a slant".
If the base circle diameter (d) and the height of the cone (h) are known, then the following procedure can be used for finding out the surface area oh the cone:
Surface area of the cone is given by:
S.A= Area of the base + lateral surface area.
S.A= p.r.r + p.r.l
where l can be determined using Pythagorean theorem.
The answer is left in the p form. As we are finding the area, the answer should be in centimeters squared.
This formula can be used for the calculation of surface area of cones with various dimensions.
