Surface Areas and Volume of 3d shapes are given here. Click to read how to find surface area and volume of different shapes such as Cube, Sphere, Cone, Cylinder and Cuboid easily with examples at BYJU'S. A Sphere is a three-dimensional solid having a round shape, just like a circle. The formula of total surface area of a sphere in terms of pi (π) is given by: Surface area = 4 π r2 square units. The difference between a sphere and a circle is that a circle is a two-dimensional figure or a flat shape, whereas, a sphere is a three-dimensional shape. In this lesson we'll look at the volume and surface area of spheres. A sphere is a perfectly round ball; it's the three-dimensional version of a circle..
