$$V=\frac{ 4 }{ 3 }\pi r^3$$
1m=39.4in
1in=2.54cm^3

D=39.4in
R=19.7in so Volume= 32,023in^3

32,023in^3 * 2.54cm^3 = 81,341cm^3 Volume

81,341cm^3 = 81,341mL

81,341mL * 0.30g/mL = 24,402.3g or 53.7lbs

So yes hopefully you could lift the cork ball

Not sure why you converted to  inches and lbs

Volume of a cork ball 1 m in diameter  = (4/3)*pi* 50^3  cms^3 

its mass =  (4/3)*pi* 50^3 * 0.3 = 157079.6 gms 

=   157.08 kg.
