Volume of a Circle formula: [tex]V = \frac{4}{3} \pi r ^{3} [/tex]
[tex]V = \frac{4}{3} \pi (3.12)^{3} [/tex]
[tex]V = \frac{4}{3} \pi (30.371328)[/tex]
[tex]V = \frac{121.485312}{3} \pi [/tex]
[tex]V = 40.495104 * (3.14)[/tex]
[tex]V = 127.15462656[/tex]
Round decimal to the nearest tenth:
127.1546256 ⇒ 127.2
Answer: V = 127.2 cubic inches
