Question $4[25$ marks$]$

Write a program to take in the radius and angle of a slice of pie. The program should calculate the area, the perimeter and the arc length of the pie slice. Then, display the output.

An example of the output interface is:

Enter the radius of the pie slice $($cm$)$: $2\mathrm{.}0$Press Enter$$

Enter the angle of the pie slice $($degree$)$: $36$Press Enter$$

The area of the pie slice is $\backslash (1\mathrm{.}257\backslash$mathrm$\{$~cm$\}^\{\backslash$wedge$\}2\backslash )$

The perimeter of the pie slice is $5\mathrm{.}257$ cm

The arc length of the pie slice is $1\mathrm{.}257$ cm
