Answer:
13.5 in, or 34.3 cm.
Step-by-step explanation:
First, use the formula volume = pi * r^2 * height- you have the volume, so just solve the equation 411pi = pi * 9 * r^2 for r, and you get that r = 6.75. Since diameter is equal to 2r, multiply 6.75 by 2 to get your answer of 13.5 inches. The questions asks for the diameter in centimeters though, which makes it 34.3 cm.

Every student would have five markers.
Step-by-step explanation:
There would be 20 students, and 100 markers which is 20/100. You would reduce that fraction to 1/5. Therefore, every student would have 5 markers.
=>(hypotenuse)^2=(base)^2+(perpendicular)^2
=>(h)^2=(15)^2+(8)^2
=>(h)^2=289
=>h=√289
=>h=17 yd
