Input angle, print tangent

Write a short program that prompts the user to enter an angle in degrees, and print it's tangent. Be sure to match the input prompt to the user and the output format exactly! Assume that the math module has been imported. For example, the execution could look like: $($user input is bolded$)$

Please enter an angle in degrees $($float$)$: $12\mathrm{.}3$

That angle's tangent is: $0\mathrm{.}218035260431029$

Sin of an angle

Write code that that sets the value o variable called sin$\_$angle to the sine of an angle in degrees. Assume that the math module has been imported and that the variable angle$\_$amount has already been defined.

Circumference of a Circle

The circumference of a circle is two times pi times the radius of the circle. Assuming the radius is already stored in a variable named radius, compute the circumference and store it in a variable named circumference. You may also assume that the math module has already been imported.
