Question

A cone has a diameter of 18 units and height of 8 units. What is its volume? 72π cubic units 216π cubic units 648π cubic units 864π cubic units

Answer 1

Answer:

216π cubic units

Step-by-step explanation:

volume of a cone = πr²h/3

r = radius = 1/2 of diameter = 1/2 of 18 = 9

volume = π*9²*8/3 = 216π
