Answer:

10.24 m

Explanation:

The volume formulas for the figures are ...

  • V = 4/3πr³ . . . sphere
  • V = 1/3πr²h . . . cone

You can fill in the given radii and set the volumes equal:

4/3π(4 m)³ = 1/3π(5 m)²h

h = (4^4)/(5^2) m . . . . . divide by the coefficient of h

h = 10.24 m

The height of the cone is 10.24 meters.
