The radius and height of a right circular cone are 6 cm and 7 cm respectively.
Find i)slant height
​

Answer 1

We have a formula:

l²=r²+h²

l²=(6)²+(7)²

l²=36+49

l²=85

l=9.21 cm

Answer 2

Let the radius be base = 6 cm

Let the height be perpendicular = 7 cm

Let the slant heigh be the hypotenuse = x

${x}^{2} = (base) {}^{2} + {(perpendicular)}^{2}$

${x}^{2} = {6}^{2} + {7}^{2}$

${x}^{2} = 36 + 49$

${x}^{2} = 85$

$x = \sqrt{85}$

$x = 9.21954446$
