Calculate the surface areas of cylinders, cones and spheres

How do I find surface area of spheres, cones and cylinders?

Just use these simple equations;

Formula for Surface Area :

Cylinder = 2πr² + 2πrL  (L is the length of the cylinder)

Cone = πr² + πrL   (L is the length from the point of the cone to the edge of the base)

Sphere = 4πr2
