6.68% of the students scored at least 19 points on this test while the 85 percentile has a test score of 24.08 points
The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:
P(x > 19) = P(z > 1.5) = 1 - P(z < 1.5) = 1 - 0.9332 = 0.0668

V of w sphere = 
r³
Multiply by 3 on either sides to get rid of the fraction.
3V = 4r³
Now divide either sides by 4 to isolate r³

Take the cube root to isolate r.
