Question

A rectangle has a diagonal of 23 and a length of 5. En 22.45 1 2 9 1 point Given the area factor of 19.16 for a cylinder, what would 3

Answer 1

Remember that whenever a figure is scaled by a factor k, then its area gets scaled by a factor of k^2 and its volume gets scaled by a factor of k^3. If the area factor for a cylinder is 19.16, then the scale factor is related to it by the following expression:

`k^2=19.16`

Then:

`\begin{gathered} k=\sqrt[]{19.16} \\ \Rightarrow k=4.377213726\ldots \\ \therefore k\approx4.38 \end{gathered}`

Up to two decimal places, the scale factor is 4.38
