A ball has a radius of 6cm.
\n" ); document.write( " Jack puts some balls in a cylindrical tank with a diameter of 24cm containing water.
\n" ); document.write( " The water level rises 8cm. How many balls are in the tank?
\n" ); document.write( ":
\n" ); document.write( "Let n = no. of balls in the tank
\n" ); document.write( "Tank radius = 12 cm
\n" ); document.write( ":
\n" ); document.write( "Total Ball vol = Tank water volume increase
\n" ); document.write( "n(\"4%2F3\"\"pi%2A6%5E3\") = \"pi%2A12%5E2%2A8\"
\n" ); document.write( "divide both sides by pi
\n" ); document.write( "n(\"4%2F3\"\"6%5E3\") = \"12%5E2%2A8\"
\n" ); document.write( "do the math
\n" ); document.write( "288n = 1152
\n" ); document.write( "n = 1152/288
\n" ); document.write( "n = 4 balls\r
\n" ); document.write( "\n" ); document.write( "
