Answer:

216πubic unit

Step-by-step explanation:

A cone is a solid shape.

Volume of cone = 1/3 πr²h

Where height(h) = 8 units and diameter = 18 units, π = 3.14

Note radius (r) = diameter ➗ 2 = 18/2 = 9 units

Therefore,.

Volume of cone = 1/3 x π x r x r x h

Volume = 1/3 x πx 9  x 9 x 8

Volume = 648π➗ 3

Volume = 216πubic unit
