Quizplus · Accepted Answer

The formula for finding the diameter of a sphere is:
diameter = 2 x radius

So, in this case:
diameter = 2 x 8.5 cm = 17 cm

Therefore, the correct answer is B) 17 cm. The formula for finding the diameter of a sphere is: diameter = 2 x radius. 
Substituting the given radius value of 8.5 cm in the formula, we get:
diameter = 2 x 8.5 = 17 cm
Therefore, the diameter of the sphere is 17 cm, and the best choice is B.
