Hi! Help me, please to solve the following problem: The diameter of an ice-cream cone is 6 cm and the slant height is 10 cm. What volume of ice-cream would fit inside the cone? Thanks!

Tamriko,

The volume of a cone is 1/3 πr^{2}h where r is the radius of the open end of the cone and h is the height. You know the radius is 6/2 = 3 cm but you know the slant height rather than the height.

What does Pythagoras theorem tell you about the height?
