Frustum of a Cone:
- Surface Area: The surface area
  
  $A$ of a frustum of a cone with radii $r_1$
  
  $r_{1}$ and $r_2$
  
  $r_{2}$ , slant height
  
  $l$ , and height
  
  $h$ is: $\pi (r_1 + r_2) l + \pi (r_1^2 + r_2^2)$
  
  $A = π (r_{1} + r_{2}) l + π (r_{12} + r_{22})$
- Volume: The volume
  
  $V$ of a frustum of a cone is: $\frac{1}{3} \pi h (r_1^2 + r_2^2 + r_1 r_2)$
  
  $V = 31 πh (r_{12} + r_{22} + r_{1} r_{2})$
Applications in Real Life:
