Problem $1-3$

Create Matlab$-$function named "circle" which calculates the circumference of a circle and the

area of the circle. The input of function is the radius of the circle $r.$ The function outputs two

values, the first $($let$\text{'}$s call it $p)$ is the perimeter and the second $($let$\text{'}$s call it $A)$ is the area of the

circle.

Problem $1-4$

You have been provided the Matlab function exampleFun$().$ This function takes a vector as an

input and calculates the arithmetic mean $("$average$"),$ maximum and minimum values of the

vector and outputs them in this order.

Call the function using $w=\left[\begin{array}{cccccc}7& 9& 4& 12& 27& 31\end{array}\right]$ as the input and store the average in the

variable named Average, maximum to variable named Max$\_$value and the minimum to variable

named Min$\_$value.
