thats me
my name is michael(17) and i am student from germany i´m working here at a math project to support pupils all ower the world.

Math Project
introduction:about the relaitionship between the skin of a can(cylinder) and a ball with the same volume

volume=0.33l (typical volume of a can)

volume of a can(math.) : r²*(pi)*h

=>

r²*(pi)*h = 0,33

volume of a ball(math.) : 4*(pi)*r³

=>

4*(pi)*r = 0,33

caption: r = radius; (pi) = 3.14; h = height;

to be continued
