    Unhappy I need help on the wetted perimeter of a pipe and these other questions!!

    Hi there, i really hope someone can help me with these questions!? my teacher is really vague and i think he gets a bit of a kick from being so, because you ask for help he laughs and says "i cant help anymore ive pretty much told you how to do it already!"

    ive took a screen shot of the questions...


    Thank you for the help as this needs to be in by tuesday!

    angle = 2π/3 180/π = 120
    wetted perimeter = /360 2πr
    = 120/360 2π 12 = 8π
    area of cross section = /360 πr
    = 120/360 π 12 12 = 48π
    volume of water = /360 πr L
    = 120/360 π 12 12 (0.7 100) length converted in cm
    = 3.36π cm
    angle of dry perimeter = (360 120) = 240
