Calculate volume and surface area of a cone

Given slant height, height and radius of a cone, we have to calculate the volume and surface area of the cone.

• Cone :
  Cone is a three dimensional geometric shape. It consists of a base having the shape of a circle and a curved side (the lateral surface) ending up in a tip called the apex or vertex. 
  

👁 Calculate volume of a cone

• Volume of a cone :
  The volume of a cone is given by the formula - 
  

volume = 1/3(pi * r * r * h)

• 
  where r is the radius of the circular base, and h is the height (the perpendicular distance from the base to the vertex).

• Surface area of a cone:
  The surface area of a cone is given by the formula - 
  

area = pi * r * s + pi * r^2 

• 
  Where r is the radius of the circular base, and s is the slant height of the cone.

Examples :

Input : 
radius = 5
slant_height = 13
height = 12
Output :
Volume Of Cone = 314.159
Surface Area Of Cone = 282.743

Input :
radius = 6
slant_height = 10
height = 8
Output : 
Volume Of Cone = 301.593
Surface Area Of Cone = 301.593

Output :

Volume Of Cone : 314.159
Surface Area Of Cone : 282.743
