Write an algorithm to compute the area of circles. Your algorithm should prompt the user to take the number of circles and their radius values. Then it should compute the areas of each circle. Finally, your algorithm will print both radius and area of all circles into the output. [N.B. you need to use iterative statement for solving the problem. Consider Pi = 3.14159] Area of how many Circles you want to compute? 3 Input: Key in radius values: 2.5 3.12 2.16 Radius is 2.5 and the Area is 19.63 Output: Radius is 3.12 and the Area is 30.76 Radius is 2.16 and the Area is 14.65 Write an algorithm to take a list of numbers from user and determine the numbers divisible by the number 7. You need to first prompt the user that how many numbers s/he wants to input and then take the numbers. After taking the numbers, you check which numbers are divisible by 7 from the list. You need to print the number along with the position of the number. Finally, you need to print how many numbers from the list is divisible by 7. If there is no number divisible by 7 then print the message "Sorry, the list doesn't contain any number divisible by 7". Input: How many numbers to input? 5 22 21 15 78 49 Output: Number: 21 Position: 2 Number: 49 Position: 5 Numbers divisible by 7 is: 2 Write an algorithm to take a list of numbers from user and determine the grade for CSCI1320 students. You need to first prompt the user to know how many students are in the class and then take the final scores in a list. After taking the scores, you check which grade the student has got based on the input score stored in the list. If the score is between or 90 and 100 then it's an "A' grade, if it's between or 80 to 89 then 'B' grade and so on. Input: How many scores to input? 5 63 71 95 52 80 Point Distribution: Grade D Grade C Grade A Output: Score: 63 Problem 1: 20 pts Problem 2: 20 pts Problem 3: 30 pts Problem 4: 30 pts Score: 71 Score: 95 Grade F Score: 52 Grade B Score: 80 neral Guideline
