1. Write a program which will accept from the user values for radius and height and will determine: a. The surface area and the volume of a cone with radius r and height h b. The surface area and the volume of a sphere with radius The program will print out the results.. 2. Write a program which will solve for X1, X2, and x3 53 + 6x2 - 5x3 = 7 3x + 2x2 = 11 X; - 25x2 3x3 = 8 3. Two forces F2=21-3+12k and F2=-5i+2j+9k are acting at the point (15,12,8). Write a program which will determine and print out: a. Sum of the forces b. The total moment of these forces about the origin 4. Define an array m by n where both are provided by the user. Perform the following operations and print out the results: a. Fill the array with random numbers in the range of -50 to 50 b. Multiply the array by a constant provided by the user c multiply the matrix by its transpose d determine the inverse of the matrix you found in (b)
