Hey guys, I really struggle to get my head around these sorts of questions, often coming up with wildly erroneous answers, however if I see the correct answer and the logic of how it was obtained, I have found it is the best way for me to learn. I really want to learn this stuff (high school dropout) and improve my math skills and hopefully one of you fine young mathematician's can assist me? Pretty please Keep up the great work!

i) CB^2 = 40^2  24^2 (Pythagoras theorem) CB=sqrt (40^2  24^2) (taking the root of both sides CB = 32 ii) Are of triangle = 0.5 *CB*AB A=384cm2 iii) Area of a circle =pir*r^2 A= 113.097cm2 All of these questions simply require a formula to substitute into. Do you have a list of formulas, ie volume and area formulas?
