find its slant height for volume of a right circular cone is 100¦Ð cm3 and its height is 12cm.

Answer 1

volume of cone = (1/3)π r^2 h

I have a feeling that your 100¦Ð is supposed to mean 100π

so (1/3)π r^2 (12) = 100π
12r^2 = 300
r^2 = 300/12 = 25
r = 5

let the slant height be s

s^2 = 5^2 + 12^2
etc
