Use your knowledge about the volumes of cones and cylinders to find a volume for a solid hemisphere of radius r.

Step-by-step explanation:

The formula for calculating the volume of any sphere is 4/3 of the cubic radius by pi, so you just have to insert the values that you are given in the problem, and you can get an answer, in this case the value for radius is "r" so we are left basically with the next solved fromula:

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17
