Question

A square sheet of paper is converted into cylinder by rolling it along its side. What is the ratio of the base radius to the side of the square?

Answer 1

side of the square will be converted to form a circle,

So,

side=circumference of circle

$\begin{array}{c}side=2\pi \times radius\\ \frac{radius}{side}=\frac{1}{2\pi }\\ =\frac{7}{44}\\ =7:44\end{array}$

Thus the ratio will be 7:44
