CONE


Cone











Definition

=>
one is a three-dimensional geometric shape that tapers smoothly from a flat, round base to a point called the apex or vertex.

=> the solid figure bounded by a plane base and the surface (called the lateral surface) formed by the locus of all straight line segments joining the apex to the perimeter of the base.
=> a shape whose base is a circle and whose sides taper up to a point.





AREA


πr2 + πrl



VOLUME


1/3 x Area of base x Height


1/3 x πr^2 x h
