I just started me java class and im confused about how powers work, such as
Volume of Cylinder = PIE (radius)2(SUPPOSED TO BE SQUARE, NOT 2) *height
how does the above translate to java code? specificly the power of 2, sry im stupid, thx

For exponents you use:
Math.pow(A, B); //A is the original number. B is to what power
Take a look at the Java Platform SE 6 class. Most notably the pow method.
I always write squares out (in my mind this is faster and more accurate, but not by much)
Mmm, PIE. It's actually PI, and you can use Math.PI for the floating point representation of this number. Also, in Java you must explicitly spell out everywhere you're performing a multiplication/add/etc.
double a = 3; double b = 3a; // error double b = 3 a; // error double b = 3 * a; // correct
Volume of Cylinder = PI(radius)2(power 2) * height
Surface Area of Cylinder = 2 PI radius * height
ok so im confused on why my teacher would give me the above as a formulas. at my level of math and java programming the above makes no sense.. i can decipher the top one. but 2 pi radius * height.. umm wtf
so its 2 * pi * radius * height? Why have one multiplication symbol and not the rest?
It isn't in parenthesis.. look at volume. o well, i got it fiqured out, i think my teachers kind of mean tho. THanks for the help everyone.
Did you see my above post?
