Question

if slant height (1) of a cone is 13cms and hight (h) is 5cms.find it volume
​

Answer 1

Answer:

390cm³

Step-by-step explanation:

base² = slant height² - h²

base² = 13² - 5² = 169 - 25 = 144

base = √144 = 12

Volume = 1/2*b*h*l = 1/2*12*5*13 = 1/2*780 = 390cm³

Therefore, Volume = 390cm³
