0 22x3
0 4773

Volume = ⅔πr³

Step-by-step explanation:

Given

Shape: Cone

Height = 2 * Radius

Required

An expression for the volume of the cone.

Let h and r represent the height and the radius of the cone, respectively.

So, h = 2r.

So solve this question, we simply write out the formula to calculate the volume of a cone.

Volume = ⅓πr²h

Substitute 2r for h.

Volume = ⅓πr²(2r)

Volume = ⅓πr² * 2r

Volume = ⅔πr³

Hence, the above expression represent the volume of a cone when h = 2r

Step-by-step explanation:

The volume of a cubic box with side length of s inches can be calculated using the following formula

If the initial side length was 3 inches and the customer asked Simon to increase each one of the sides of the box by one inch, then the new side lengths now become 4 in (3+1 = 4)

Therefore the final and new volume is
