A sphere is a three-dimensional space, such as the shape of a football. A sphere is a body bounded by a surface whose every point is equidistant (i.e. the same distance) from a fixed point, called the centre or the origin of the sphere.

What is the surface area of this sphere? Use π ≈ 3.14

Find the radius of the sphere.

radius = Use this number in the surface area formula. Use π ≈ 3.14.
