a) The average arithmetic mean is calculated by adding all of the values and then dividing the sum by the total number of values.

Which is 200.3.

b) Assume that the new average mean is 201, then

Solve for x.

Divide by 2604 to solve for x.

So the height of the new player is 175 cm.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
