Answer:

1.024 cm

Step-by-step explanation:

volume of Sphere is given by; V=4/3(πr³).

by making r subject of formula, the equation for r is;

r=³√(3v)/4π

given from question that V=4.5cm³, π=3.14, substituting the values in the equation for r,

we have that;

r=³√[3(4.5)]/[4(3.14)]

r=1.024 cm ( 2 significant figures?
