Question 566035: ok i have ABSOLUTLEY NO CLUE WHAT TO DO I AM SOOO LOST ! PLEASE SOMEONE HELPME!!
Find the radius of the right cylinder shown, in which the height of the cylinder is equal to the diameter.
ok, soo what i did is find the surface area.
S=2*pi*radius^2+28pi*raduis
so i plugged in the numbers
150pi=2pir^2+2pir(2r)
after that i dont know what todo.. HONESTLEY i dont even think i did it right...

Question 544815: Hello,
I am trying to imagine using three flash lights in a ball to light it up without changing the balance of the ball (too much). If the end of each light is at the center, could they be positioned to be equidistant from each other?
If it were just a single plane, then the angle between each would be 120 degrees. How should two be rotated along other planes to have the ends be equidistant in space?
Thanks!
