The distance from the top of the cone to the edge is 15 feet. The height of the cone is 6 feet. What is the radius of the cone?

Answer 1

r^2 = 15^2 - 6^2 = 225 - 36 = 189

r =sqr189 = 17 feet = the radius of the cone

the height and radius form 2 sides of a right triangle with hypotenuse = 15 feet
