Question

Radius of base(r)9cm and perpendicular height12cm of cone is given .Find its slant height (l);​

Answer 1

Answer:

Step-by-step explanation:

Given: Height (h) = 12 cm, length (l) = 13 cm  To find: Radius of the base of the cone (r) l2 = r2 + h2  ∴ 132 = r2 + 122  ∴ 169 = r2 + 144  ∴169 – 144 = r2  ∴ r2 = 25  ∴ r = √25 … [Taking square root on both sides]  = 5 cm  ∴ The radius of base of the cone is 5 cmRead more on Sarthaks.com - https://www.sarthaks.com/852954/perpendicular-height-cone-is-12-cm-and-its-slant-height-13-find-the-radius-the-base-the-cone
