Given: 

Volume of cone = 105 cubic units

Radius = 5 units

Formula used : volume of cone = ⅓πr²H

Putting value in formula, we get

105 = ⅓ × 22/7 × 5² × h

105×3×7 = 22 ×25 × h

2205 = 550 × h

Dividing both sides by 550, we get

2205/550 = 550 × h/550

h = 4

 

Thus, height of cone is 4 units.
