Surface Area Of A Cone Formula Explained

Surface Area Of A Cone FormulaFormula. The basic formula when slant height and radius are known is: Surface Area of Cone. Derivation. Let us consider a cone with radius r, circumference c, and slant height s. So, C = 2πr, And Base Area (B) of the cone = πr 2. Now, we unroll the lateral face of the cone first. The formula for the Surface Area of Cone Formula is given as large Curved Surface Area of cone pi rs large Total Surface Area of cone pi r left s r right Where r is the radius of cone h is the height of cone s
