spheer surfus area=4*pi+rad*rad... area=3.980 cm^2, so r^2=3.980/4pi... r^2=3.980/12.5663706=0.316718337... so radius=root(0.3167....)... radius=0.562777342... VOLUME av spheer=(4/3)pi*rad^3... =(4/3)*3.1415926535*(0.562777342)^3... OR... volume=(radius/3)*area... =3.98*0.562777342/3... =0.74661794... volume bout =0.75 cm^3
