The only way to determine whether or not an outcome is unusual or not is to compare it with previous or future outcomes.
You would have to know the height of the 8th graders
20 * (31/100) = 21*0.31=6.51
20.00-6.51=13.49

The diameter fits all the way across the circle, and the radius fits half way across the circle, thus making the radius half the length of the diameter so the ratio for diameter/radius would be 2/1 or 1/.5
Answer:
True.
Step-by-step explanation:
Volume of a cylinder = π r^2 h where h = height and π r^2 = the base area.
Volume / height = π r^2 h / h = π r^2 = base area.
