Question

What is the volume in cubic inches of the candle

Answer 1

`V\approx21in^(3)`

1) The volume of a cylinder is given by a formula. This one down here:

`V=\pi\cdot r^2\cdot h`

2) Note that the Diameter is twice the radius, therefore it is safe to say that the radius is 1.5"

3) So we can plug these data into the formula this way:

`\begin{gathered} V=\pi\cdot(1.5)^2\cdot3 \\ V=\pi\cdot2.25\cdot3 \\ V=3.14\cdot2.25\cdot3 \\ V=21.2057\ldots \\ V\approx21in^(3) \end{gathered}`
