Question

4. Write a function with header (A, V - myCone (r, h), which outputs the total area A and volume of a cone with base radius r and height h. 5. Write a function - myMatrix (myvec, m, n) which creates an m-by-n matrix A, as in Problem 3, but for arbitrary values of mand n and any length of vector myvec. Hint: the function can use the built-in Matlab functions length, mod, and reshape, as well as either a repmat function or a loop. 6. Define an anonymous function heron which calculates the area of a triangle with sides a, b, and cusing Heron's formula. Use this function to calculate the area of a triangle with sides a = myvec (1) + myvec (2). myvec (1) +myvec (3), and c-myvec (2) +myvec (3), where myvec is your answer to Problem 1. 7. Write a function x = realRoots (a, b, c) which outputs real roots of the quadratic equation ax + bx + C = 0. If there are no real roots, then the output is x - 1). Demonstrate the performance of your function on three examples which generate two, one, and no real roots. 8. Consider a triangle with vertices at (-1,0),(1,0), and (0.1). Write a function with the headers - inside Triangle (x,y) where s is the string 'outside if the point with coordinates (x, y) is outside the triangle, 'border' if the point is exactly on the border of the triangle and inside if the point is inside of the triangle. Test you function on the following cases: (x, y)=(-0.5, 0.5).(-1, 1), and (0,0.5).

Answer 1

ANSWER OF QUESTION 4

%-------------AREA AND VOLUME OF CONE FUNCTION--------------------------------------------------------%;
function [A,V] = myCone( r,h )
r=input('Enter the radius of cone :' )
h=input('Enter the height of cone :' )
s=sqrt(h*h+r*r);

% Calculate Area of cone (areaC)
AreaC = [(3.14)*(r*s+r*r)]

% Calculate volume of cone (areaC)
VolumeC = [(1/3)*(3.14)*(r*r*h)]

OUTPUT:

Enter the radius of cone :r = 2
Enter the height of cone :h = 3
AreaC = 35.203
VolumeC = 12.560
