Answer:
Step-by-step explanation:
The main difference is that for a sphere all of its points are an equal distance from the center and is what causes its round shape. This allows for the formula to be very simple [tex]4\pi r^{2}[/tex]. Cones and Cylinder's on the other hand have both rounded/curved faces and flat faces with different length from the center. This means that you need to take this into account when calculating the surface area which is why their formula's are more complex.
