Answer:

1018.28

Given -

Diameter of cone = 18 cm

To get the radius divide it by 2 -

Radius, r = 18/2 = 9

height, h = 12 cm

To find -

Volume of cone.

Solution -

Volume = 1/3 hπr²

→ V = 1/3 18 × 22/7 × 9 × 9

→ V = 7128/7

→ V = 1018.28

Therefore, the volume of the cone is 1018.28.

Answer:

324π

Step-by-step explanation:

The volume of a cone is πr^2 * h/3. To find the radius, we do the diameter (18) divided by 2 to get 9 as the radius. If we plug the values into the equation, it ends up looking like: π9^2 * 12/3. This can be simplified to 81π*4, and 81*4 is 324. Multiply that by π to get an exact form of 324π.
