Question

The slant height of a right circular cone of height 15 cm and base diameter 16 cm is

Answer 1

Step-by-step explanation:

Given:- Base diameter of a cone = 16cm

Radius (r) of a cone = 16/2 = 8 cm.

Height (h) of a cone = 15 cm

Let the slant height of a cone be 'l'.

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

$= \sqrt{( {8)}^{2} + ( {15)}^{2} }$

$= \sqrt{64 + 225}$

$= \sqrt{289}$

$= 17 \: cm$

Answer:- The slant height of a cone is 17 cm.
