Question

An ice cream company needs to know how much ice cream can fit into itsnew ice cream cones.

Answer 1

The formula for the volume of a cone is :

`V=(\pi r^2h)/(3)`

From the given problem :

the radius is 5cm and the height is 12

Substitute this values to the formula :

The correct answer is Choice B.

Now for the tip

The volume of any solid is always :

V = Area of the base x Height

Note : If the solid or a 3D object is pointed, just divide it by 3

So the volume of this cone is :

Area of the base (Circle) = πr^2

height is h

And since it is pointed divide it by 3

That's the formula for the cone shown above became like that

Now for a cylinder

Area of the base (Circle) = the same area above

height is h

And it is NOT pointed so dont divide it by 3

The volume will be : V = πr^2h
