Question

About how many cubic inches of water does the glass hold?

Answer 1

Step-by-step explanation

Given that;

The height of the glass is 8in

The radius of the glass is 2.5in

Follow the steps below to find the volume of the glass

Recall, that the shape of the glass is cylindrical

Hence, the volume of a cylinder is given as

`\text{ V = }\pi*\text{ r}^2\text{ }*\text{ h}`

Substitute the given data into the formula above

`\begin{gathered} \text{ let }\pi\text{ = 3.14} \\ \text{ V = 3.14 }*\text{ \lparen2.5\rparen}^2\text{ }*\text{ 8} \\ \text{ V = 3.14 }*\text{ 6.25 }*\text{ 8} \\ \text{ V = 3.14 }*\text{ 50} \\ \text{ V = 157 in}^3 \end{gathered}`

Therefore, the volume of the cylinder is 157 cubic inches
