Answer:
Difference of volume of air = [tex]17182.08cm^{3}[/tex]
Step-by-step explanation:
Radius of ball = 18 cm
Volume of big ball = [tex]\frac{3}{4} \pi o^{3}[/tex]
= 4/3 x * 14 X 18[tex]^{3}[/tex]
= 7324g * g2/ 3
= 24416.64cm^3
Radious of another (small ball) = 12 cm
Volume of small ball = [tex]\frac{3}{4} \pi R^{3}[/tex]
= 4/3 x 3 * 14 X 12^3
= 21703.68/ 3
= 7234 * 56cm^3
Difference of volume = [tex]v_{b} -v _{s}[/tex]
= 24416 * 64 - 7234 * 56cm^3
= 17182 * 08 cm^3
