Step by Step Solution

Step 1

The picture below shows the sphere with the radius 7cm.

Step 2

To calculate the volume, we can use the formula for the volume of a sphere. Note that r is the radius of the sphere.

Step 3

Since the values for r, and π are given, we can substitute r with 5 and π with 3.14. After substituting these values, we can calculate V as shown below:

Step 4

Now, the calculated number 1436.03 carries no meaning unless we include the unit for it. Since the radius is in cm, the unit for volume will be cm^{3}. Hence:
