Answer: V≈18887 cm³.
Step-by-step explanation:
The circumference L is 126 cm.
Hence, L=2πr.
126=2πr
2*63=2*πr
Divide the equation by 2π:
[tex]\displaystyle\\\frac{126}{2\pi } =r\\\\\frac{63}{\pi } =r\\\\20,05\ cm \approx r\\\\V=\pi r^2h\\r\approx 20,05\ cm\ \ \ \ height\ h=15\ cm.\\Hence,\ \\V=\pi *(20,05)^2*15\\V=\pi *20,05*20,05*15\\V=\pi *6012\\V\approx18887\ cm^3.[/tex]
