Answer:

1,000cm

Step-by-step explanation:

I just did the practice. I got it right.

Answer:

[tex]1000cm^{3}[/tex]

Step-by-step explanation:

Use formula [tex]V = \frac{4}{3} \pi r^{2}[/tex]. Substitute 6.2cm for r (radius).

[tex]V = \frac{4}{3} \pi (6.2)^{3}[/tex]

[tex]V=\frac{4}{3} \pi 238.328[/tex] Multiply 238.328 and pi.

[tex]V=\frac{4}{3} 748.7294939447[/tex] Multiply748.7294939447 and 4.

[tex]V=\frac{2994.9179757788}{3}[/tex] Divide by 3.

[tex]V=998.3059919263[/tex] Round up to [tex]1000cm^{3}[/tex]
