Question

Use the formula to solve the problem. Round to the nearest hundredth. Volume of a sphere: V = 4/3r3 Surface area of a sphere: A = 4r2 Find the surface area of a sphere with a radius of 1 inch. cubic in.

Answer 1

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

V = 4/3 (3.14)

V = (4*3.14) /3

V = 12.56 / 3

V = 4.19

Answer 2

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.
