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

Answer»

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.
