A cone jas a volume of 40 cubic inches and 8 inches tall follow the steps to find the base of the cone

Area of the base = 15 in.²

Step-by-step explanation:

Volume and height are given, which we can use to find the radius of the base. We can use the formula for the volume of a cone.

 Substitute the known variables.

 Multiply both sides by .

 Now we have which is the area of the base.

Area of the base = 15 in.²

15 inches

Step-by-step explanation:

The volume of a cone is denoted by: V = , where r is the radius and h is the height. Here, we already know that V = 40 and that h = 8, so plug these in to find πr², which is the area of the base:

V =

40 =

πr² = 15

The area of the base of the cone is 15 inches.
