How do you find volume of sphere, cylinder, cone ? ... explaining please
boyakko [2]

Answer:

hmmmm

Step-by-step explanation:

Cone

The volume of a cone is linked to the volume of a cylinder. A cone is one third of the volume of a cylinder. The volume of a cone is ¹/₃ × π × r² × l. To calculate the volume we multiply these values together. The answer will be written in units³.

Sphere

The volume of a sphere is ⁴/₃ × π × r³. To calculate the volume we multiply these values together. The answer will be written in units³.

Cylinder

The volume of a cylinder is π × r² × l (r is the radius of the circle and l is the length of the cylinder). To calculate the volume we multiply these values together. The answer will be written in units³. It is more accurate to use π = 3.142 or the π button on a calculator.

   A cone is a 3D shape with 2 faces and one edge

   A sphere is a 3D shape. It has one continuous face and no edges

   A cylinder is a type of prism. It has 3 faces and 2 edges
