Using C code, calculate the following problem and have your code display the answer to two

decimal places. Find the surface area of a cone where $r=5,h=12$ and the equation for the surface

area, $A,$ is shown below

$A=r(r+\sqrt[\phantom{2}]{h^2+r^2})$

Using $C$ coding, and a user input for polar coordinates of a point $(\text{'}r\text{'}$ for radius and $\text{'}a\text{'}$ for angle

in degrees$),$ generate and print the Cartesian coordinates. An angle $\text{'}a\text{'}$ in degrees is converted to

radians by the formula: theta $={}^{**}\frac{a}{180}.$ Given the radius, $r,$ and the angle, theta, in radians, the

Cartesian coordinates are calculated as follows

$x=r^{**}cos($ theta$),y=r^{**}sin($ theta$).$

Using C coding and a user input for a student grade, use a SWITCH$/$CASE to print out the

following:

'Grade is A$.\text{'}$ for student grade $90$

'Grade is B$.\text{'}$ for student grade $<mn>9</mn><mn>0</mn>$ and student grade $80$

'Grade is C$.\text{'}$ for student grade $<mn>8</mn><mn>0</mn>$ and student grade $70$

'Grade is D$.\text{'}$ for student grade $<mn>7</mn><mn>0</mn>$ and student grade $60$

otherwise 'Grade is E$.\text{'}$

Using $C$ coding, create and even array $(10,12,14,16,18)$ and an odd array $(9,11,13,15,17)$

use a FOR loop to create a total array $(9,10,11,12,13,14,15,16,17,18)$ by rearranging the

elements in the previously created odd array and even array. Next, use a WHILE loop to print out

the values of the total array in a single vertical column.

$2)$ Using C coding, and a user input for polar coordinates of a point $($r$$ for radius and $$a$$ for angle in degrees$),$ generate and print the Cartesian coordinates. An angle $$a$$ in degrees is converted to radians by the formula: theta $=$ pi$*$a$/180.$ Given the radius, r$,$ and the angle, theta, in radians, the Cartesian coordinates are calculated as follows

x $=$ r$*$cos$($theta$),$ y $=$ r$*$sin$($theta$).$
