Answer to Problem 3.1P

Solution:

The created variable C is “C = 79.587”.

Explanation of Solution

The formula to calculate the circumference of a circle is,

C=2πr

Here, the radius of the circle is r.

Consider, the radius is r=2.

Substitute 2 for r in the above formula.

C=2π(2)=4π=12.5664

MATLAB Code:

clc

clear all

close all

r = 2;

% Define the variable r.

C = (2*pi*r)

% Define the variable circumference.

Save the MATLAB script with name, chapter3_54793_3_1P.m in the current folder. Execute the script by typing the script name at the command window to create a variable C and store circumference in it, define the variable r and define the variable C.

Result:

MATLAB: A Practical Introduction to Programming and Problem Solving, Chapter 3, Problem 3.1P

Therefore, the created variable C is “C = 12.5664”.
