The ratio between the slant height and perpendicular height of a cone is 5:4.The radius of the base of the cone is 6cm.How to find slant height of cone?

Answers

Answered by Reiny
let the perpendicular height be 4x
let the slant height be 5x

(4x)^2 + 6^2 = (5x^2
16x^2 + 36 = 25x^2

carry on, of course you would reject the negative value of x after taking the square root at the end.
