Vedclass · Answer

(C) In a right circular cone,the slant height $(l)$,the vertical height $(h)$,and the radius of the base $(r)$ form a right-angled triangle.According to the Pythagorean theorem,the square of the hypotenuse is equal to the sum of the squares of the other two sides.Therefore,$l^{2} = h^{2} + r^{2}$.Taking the square root on both sides,we get $l = \sqrt{h^{2} + r^{2}}$.
