Answer:
Basketball = 12.02 Tennis Ball = 3.32 cm
Step-by-step explanation:
You know how in a 2d circle, its radius is the same distance from the center point to its edge? Well, the same thing is true in a 3d sphere. The legs of the triangle created in the diagram are both radii of the sphere. So, they are both the same distance.
You can signify this by making each radius equal to x. You then use the Pythagorean theorem, [tex]a^{2} +b^{2} =c^{2}[/tex], to solve for the radius.
Basketball:
x^2+x^2=17^2
2x^2=289
x^2=144.5
x = [tex]\sqrt{144.5}[/tex]
x =12.02 cm
Try the same steps for the tennis ball
