please help me with this

Answer:
A) 2481.156[tex]\pi[/tex] cm³
Step-by-step explanation:
The formula for volume of a sphere is: [tex]\frac{4}{3} \pi r^{3}[/tex]. In this case, the radius is 12.3. 12.3 cubed is: 1860.867. 1860.867 x 4 is 7443.468. 7443.468 divided by 3 is 2481.156. Since we haven't multiplied by pi yet, the answer would be 2481.156[tex]\pi[/tex].
Hope it helps!
