Question

Based on your understanding of function M-file, create a function that can compute the volume of a cylinder. Execute your function file for (radius, height) values of (2,5), (3,7) and (5,10)

Can someone help me with this? It is for Matlab.

Answer 1

The above problem can be solved in the following steps-

STEP 1- First define the function volume_of_cylinder(radius, height) in the filename volume_of_cylinder.m.

This has to be done because script name and function name should be same.

STEP 2 - This function takes in two input parameters, radius and height and returns volume value

STEP 3- In the funciton, using the formula $vol = \Pi r^{2}h$ we compute the volume of cylinder

STEP 4- After executing the script file, we will call the funtion defined above from the command window with different radius and height values and see the output as shown below.

MATLAB CODE-

volume_of_cylinder.m

%define the function to calculate the volume of cylinder
%it takes in radius and height as input parameters
%and returns volume as vol of cylinder
%formula is volume of cylinder = pi * r^2 * h
function volume = volume_of_cylinder(radius, height)
%using the formula to compute the volume of cylinder,
%store the volume in the returning variable
volume = pi*(radius^2)*height;
end

OUTPUT-

On the command window, call the defined function volume_of_cylinder() with the radius and height values as shown below

Command Window >> volume of cylinder (2,5) ans = 62.8319 >> volume of cylinder (3,7) ans = 197.9203 >> volume of cylinder (5,10) ans = 785.3982 fx >>|
