14.7 mm is the height.
Use the volume equation for a cylinder which is
volume=(PI/4)*(diameter^2)*(height)
And you have volume, and diameter (which is just radius times 2) so solve for height.
5588=(PI/4)*(22^2)*Height
Height = 14.7 mm

There are 63 students in the room because 21 x 3 = 63
Just plug in a 4 wherever you see a k.
5*4+6 (multiply first)
20+6
So the answer is 26
8 11/12 To solve this you have to convert 8 1/6 to 8 2/12 and 3/4 to 9/12. 8 2/12 + 9/12 =8 11/12
