Question

Find the slant height of the cone to the nearest whole number.

The cone has a height of 19m,

And a radius of 10m

Thanks!

Answer 1

slant height is given by pythagoras theorem

h^2 = 19^2 + 10^2
then take sq root

Answer 2

apply Pythagoras's theorem
sqrt 19 ^2 - 10^2
16.15 m slant height
