x=(5.13.7)(3.4+4.2)23.27.12.2 Assign the result for x to the variable x. y=43+5235.764.16.03 Assign the result for y to the variable y. z=(2.1+8.0)1/3 Assign the result for z to the variable z. Problem 2 Area of a circle is defined by the following formula: A=r2 Circumference of a circle is defined by the following formula: C=2r Write commands to compute the area and circumference of a circle with radius 2 and assign them to the variables A and C, respectively. Be sure to use a MATLAB command to evaluate each mathematical expression rather than just entering the result calculated elsewhere (e.g. a local MATLAB session or on your calculator)
