1. Calculate the volume and surface area for 12 different Spheres by randomly choosing different radii.

2. Find the missing dimesion. Round to the nearest unit.
a. Sphere: volume 293 unit³, diameter___ units

b. Sphere: surface area 98.5 unit², radius___ units

3. Packaging: Tennis balls with a diameter of 3 units are sold in cans of three.
The can is a cylinder. What is the volume of the space in the cylinder not
occupied by tennis balls? Assume the balls touch the can on the sides, top,
and bottom.
