    V = 4/3 (3.14) (1^3)

    V = 4/3 (3.14)

    V = (4*3.14) / 3

    V = 12.56 / 3

    V = 4.19

    We are given with the equations for the volume of the sphere and area of the sphere such as shown below:

    Volume of sphere = 4/3 r³

    Area of the sphere = 4r²

    We need to solve for the area if radius = 1 inch and the solution is:

    Area of the sphere = 4 (1) ²

    Area of the sphere = 4 inch²

    The answer is 4 inches².
