Department of Computer Science & Engineering Practice 1 Write a program to calculate the volume and surface area of a sphere from its radius, given as input. Here are some formulas that might be useful: V = 4/3𝜋𝑟 A = 4𝜋𝑟 3 2 컴퓨터의 개념 및 실습 Practice 2 Two points in a plane are specified using the coordinates (x1,y1) and (x2,y2). Write a program that accepts two points and determines the distance between them. Distance = (𝑥2 − 𝑥1)2 +(𝑦2 − 𝑦1)2 컴퓨터의 개념 및 실습 Practice 3 Write a program that distinguish whether the input numbers are integer or not. The program should first prompt the user for how many numbers are to be entered. It should then input each of the numbers and print whether it is an integer number or not. * Integer does not mean the type of variable in this problem. For example, the program should consider 3.0 as an integer number. 컴퓨터의 개념 및 실습 Practice 4 A Fibonacci sequence is a sequence of numbers where each successive number is the sum of the previous two. The classic Fibonacci sequence begins: 1, 1, 2, 3, 5, 8, 13, … Write a program that computes the nth Fibonacci number where n is a value input by the user. For example, if n = 6, then the result is 8. 컴퓨터의 개념 및 실습
