Question

A sphere has a diameter of 3.5 inches what's the volume?

Answer 1

`\begin{gathered} D\text{ = 3.5} \\ r\text{ = }(D)/(2)\text{ = }(3.5)/(2)\text{ = 1.75} \\ \text{Volume of a sphere = }(4)/(3)*\pi* r^2 \\ \text{ =}(4)/(3)*(22)/(7)*(1.75)^2^{} \\ \text{ =}(26.95)/(21)\text{ =12.83} \end{gathered}`

Final Answer = 12.83
