Question

Which is closest to the volume of a ball with a diameter equal to 8.5 inches? O 285.7 in 3 O 352.4 in O 300.5 in O 321.4 in3

Answer 1

`\begin{gathered} D\text{ =8.5} \\ r\text{ = }(D)/(2) \\ r\text{ = }(8.5)/(2) \\ r\text{ = 4.25 in} \\ \text{Volume of a ball/Spherical = }(4)/(3)*\pi* r^3^{} \\ \text{Volume = }(4)/(3)*(22)/(7)\text{ }*(4.25)^3 \\ \text{Volume = }(6755.375)/(21)\text{ = 321.68} \end{gathered}`

The FInal answer is 321.68
