Question

What is the slant height of this circular cone with a radius of 3 and a height of 4?

Answer 1

it's basically a triangle. the "slant" would be the hypotenuse of a triangle. use pythag. theorem :a^2 + b^2= c^2 . 3^2 + 4^2 = c^2. The answer should be 5.

Answer 2

That is so simple, you have a right angel triangle with base equal to 3 and height is 4, then the slant height will be

H = (3^2 +4^2)^1/2 = (25)^1/2 = 5
