Activity B (continued from previous page) 4. Measure: Return the block to the cabinet and drag out the large sphere. The volume of a
sphere is calculated using the following formula:
VSphere = 473/3
The symbol it represents the number pi, which is about 3.14. The letter r stands for the
radius of the sphere, which is the distance from the center of a sphere to its surface. The
radius is exactly half of the diameter, which is the distance across the sphere. (The
diameter is also equal to the length, width, and height of the sphere.)
A. Place the ruler over the sphere. What is the diameter of the sphere?
B. What is the radius of the sphere?
C. What is the volume of the sphere?
