What is the volume of a cone that has a diameter of 18 centimeters and a height of 12 centimeters?

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.

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
