Answer:
1.024 cm
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?
