Answer:
Step-by-step explanation:
The total volume of the shaded and white is:
[tex]\frac{1}{3} \pi r^{2} h = \frac{1}{3} \pi (\frac{20}{2})^{2} *23=\frac{2300}{3} \pi (yd^{3} )[/tex]
The total volume of the white is:
[tex]\frac{4}{3} \pi r^{2} = \frac{4 * 7^{3}}{3} \pi=\frac{1372}{3} \pi (yd^{3} )[/tex]
The total volume of the shaded is:
[tex]\frac{2300}{3}\pi -\frac{1372}{3} \pi =\frac{928}{3} \pi (yd^{3} )[/tex]
Symbol:
h : the height
r : the radius
[tex]yd^{3}[/tex] : unit
[tex]\pi[/tex] : pi
