A right circular cylinder with a height of 20 cm and a right circular cone share a circular base and have the same volume. What is the height of the cone?

  • Math -

    Cone V = 1/3π(r^2)h

    Cylinder V = π(r^2)h

    1/3π(r^2)h = π(r^2)h

    Dividing both sides by π(r^2) and inserting value for h:

    1/3h = 20

    h = ?

  • BIOLOGY -

    20
