Answer 2

Answer:

Step-by-step explanation:

1 . Sphere :

    $Surface \ Area = 4\pi r^2\\\\ Volume = \frac{4}{3} \pi r^3$

  Variable is ' r '

  Others Constants.

2. Cone :

   $Surface \ Area = \p r^2 + \pi rs$          $[ \ s = \sqrt { r^2 + h^2 } \ , r = base \ radius, h = height \ ]$

    $Volume = \frac{1}{3} \pi r^2 h$

   Variables are ' r ' and ' h '

   Others constants.

3. Cuboid ( Rectangular Prism )

   $Surface \ Area = 2 ((l\times b) + ( b \times h) + ( l \times h)) \\\\Volume = l \times \ b \times \ h$

   Variables : l , b , h

   Constant is 2

4.  Cylinder

     $Surface \ Area = 2 \pi r h + 2 \pi r^2 \\\\Volume = \pi r^2 h$

    Variables : ' r  ' and ' h '

   Others constants..
