Question

The relation between l, r, h in a cone is

Answer 1

Answer:

the relation is:

$l^2=h^2+r^2\\\\l=\sqrt{h^2+r^2}$

Step-by-step explanation:

'l' denote the slant height of a cone.

'h' denote the height of a cone.

'r' denote the radius of base of a cone.

as we know that height is perpendicular to the base of a cone so we can use Pythagorean theorem to find a relation between l,h and r.

The relation is given as:

$l^2=h^2+r^2\\\\l=\sqrt{h^2+r^2}$.

Answer 2

the relation is:

Step-by-step explanation:

'l' denote the slant height of a cone.

'h' denote the height of a cone.

'r' denote the radius of base of a cone.

as we know that height is perpendicular to the base of a cone so we can use Pythagorean theorem to find a relation between l,h and r.

The relation is given as:
