Late Policy:$$ No submissions will be accepted after the deadline.

This is a make$-$up exercise that can be used to replace your score on In$-$class Exercise $12-2$ if you missed the synchronous lecture, or got the incorrect answer.$$ You are welcome to submit it for extra practice even if you don$$t need the points.$$ The grading is entirely automated, and you can resubmit as many times as you want up until the deadline.$$

Unlike the homework and quizzes, there are no restrictions on collaboration for make$-$up exercises $-$ you can freely work as a team with other students and show each other your answers.$$ You can also ask the TAs for help via office hours or the email alias.

Exercise $12-2$

Write a class Cylinder that contains information about a cylindrical object.

The Cylinder class must have two instance variables:

self.r is a floating point value describing the radius of the cylinder

self.h is a floating point value describing the height of the cylinder

The Cylinder class should also have a constructor and two methods:

$\_\_$init$\_\_($self$,$ diameter, height$)$ takes in two parameters other than self, representing the diameter of the cylinder, and the height, and uses this information to set up self.r and self.h$.$ Note that to get the radius $($self$.$r$)$ from the diameter, you$$ll need to divide by $2.$

get$\_$surface$\_$area$($self$)$ returns the surface area of the cylinder, given by the formula:

$$A $=2$r$2+2$rh

You should import math and use math.pi to get an accurate value for

get$\_$volume$($self$)$ returns the volume of the cylinder, given by the formula:

$$V $=$ r$2$h

Submit your code to gradescope in a file called ex$12-2.$py$.$

Examples:

if $\_\_$name$\_\_==\text{'}\_\_$main$\_\_\text{'}$:

$$c$1=$ Cylinder$(10\mathrm{.}0,20\mathrm{.}0)$

$$print$($c$1.$r$)$ #$5\mathrm{.}0$

$$print$($c$1.$h$)$ #$20\mathrm{.}0$

$$print$($c$1.$get$\_$surface$\_$area$())$ #$785\mathrm{.}3981633974483$

$$print$($c$1.$get$\_$volume$())$ #$1570\mathrm{.}7963267948967$
