Surface area=πr(r+√r^2+h^2)
\n" ); document.write( "12π(12+√144+h^2)=300π
\n" ); document.write( "12+√144+h^2=25
\n" ); document.write( "√144+h^2=13
\n" ); document.write( "144+h^2=169
\n" ); document.write( "h^2=25
\n" ); document.write( "h=5ft
\n" ); document.write( "Height of the cone=5ft.
\n" ); document.write( "Volume of the cone=1/3π*r^2*h=240π cubic feet. \n" ); document.write( "
