    v=4TTr3/2

    should look like this: v = (4/3)PI(r)^3

    now for question 1) , plug in the radius of the orange for r... like this... v = (4/3)PI(5)^3

    ok, so if you want to know the portion that is edible, minus the portion that is not edible, namely 0.5... so now use a radius of 4.5cm and you'll have it...

    cool, so you need to know the volume of the whole orange, and the volume of the edible part to find the percentage.. Please post the two volumes, and then we'll find the percentage that is edible..

    volume of the whole orange = 523.60 volume of the edible part = 380.51

    523.6 is the whole and 381.7 is the part of the edible part...

    I didn't get 380.70 I got 381.7 anyway, now we ask "what percent of 523.6 is 381.7" that equates to: x(523.6) = 381.7

    now dividing both sides gives 0.72899... and moving the decimal to percent.. 72.899% and rounding... 73% of the orange is for eats.. but personally I like the peel!!! lol

    oh, the x is "what percent" "what percent" is x of (means times) is means (equals) what percent of bla1 = bla2 x times bla1 = bla2 x(bla1) = bla2 x = bla2/bla1

    You'll get it.. learn to turn what you can say into algebra expressions. It gets easy with practice just like speaking! :)
