Question

the person use the cone shaped cup to get some water from a dispenser. the cone has a height of 5 inches in a diameter a 4in what's the closest Value to the nearest inch the cone can hold

Answer 1

To calculate the volume of the cone we use its formula and the values given.

`\begin{gathered} V=(\pi\cdot r^2\cdot h)/(3) \\ r=\text{radio = 4/2 in= 2 in} \\ h=\text{height }=5\text{ in} \\ V=(\pi\cdot(2)^2\cdot5)/(3)in^3\text{ (Replacing in the equation)} \\ V=(62.83)/(3)in^3(\text{Multiplying)} \\ V=20.94\text{ }in^3\text{(Dividing)} \\ \text{The answer is 21 in}^3\text{ after rounding to the nearest inch. } \end{gathered}`
