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;
