Answer:
area = 2.14 * 3 ** 2
Explanation:
No clue what language you use but this should be pretty universal. To find the area of a circle you use pi(r) ^ 2 or pi times radius squared
[tex]\pi r^{2}[/tex]
In python it looks like this:
>>> area = 3.14 * 3 ** 2
>>> print(area)
28.26 <Printed text
[Exceptions, Function calling another function] Write a function ticker() that first runs (calls) read_ticker() and then stores the returned dictionary. It then runs an interactive loop with the user in which the user is prompted for a company name. If the company name (key) is in the dictionary, then its ticker form and the IPO year is printed. Otherwise a warning is printed that the company name is not in the list. If the user just hits return without entering a name, the loop stops.
this is the function that needs to be called:
def read_ticker():
d = {'1347 Capital Corp.': ('TFSCW', '2014'), '1347 Property Insurance Holdings, Inc.': ('PIH', '2014'), '1-800 FLOWERS.COM, Inc.': ('FLWS', '1999')}
return d
def read_ticker():
d = {'1347 Capital Corp.': ('TFSCW', '2014'), '1347 Property Insurance Holdings, Inc.': ('PIH', '2014'),
'1-800 FLOWERS.COM, Inc.': ('FLWS', '1999')}
return d
def ticker():
di = read_ticker()
while True:
try:
name = input("Enter the name of a company: ")
if name == "":
return
print(di[name])
except KeyError:
print("Name not found! Please enter a valid name!")
ticker()
I hope this helps!

What will be displayed in the console when the following program runs?
var count = 0
while (count != 5){
console.log(count);
count = count + 2;
}
Answer:
The integer, count, will be stuck in a infinite while loop, and the console will keep adding 2 to count, so it'll look something like this.
0
2
4
6
8
10
12
14
and so forth...
Explanation:
The while loop will never stop because count can not equal to 5 because you can't add 2 to another multiple of 2 to get 5.
Because count cannot reach 5, and you cannot add 2 to another multiple of 2, the while loop will never come to an end.
What displayed in the console when program runs?An endless loop is a section of code that never reaches the ending condition, hence it keeps running indefinitely. An infinite loop may cause your software or browser to crash or freeze. Infinite loops must be understood in order to avoid such situations.
When a condition always evaluates to true, an infinite loop happens. Typically, this is a mistake. You may, for instance, have a loop that decreases until it hits zero.
Therefore, It will resemble this because the integer count will be locked in an unending while loop and the console will keep adding 2 to count. 0, 2,4, 6, 8, 10,12, 14 The program will end in an infinite loop.

[Files, for loops, exceptions; 20pt] Using a for loop, write a function called countWord(). It takes 2 parameters: The name of a text file (e.g. gettysburg.txt that is included with this test) and a word to be searched within that file. Your code should return the number of times the given word appears in the file. Capitalization should not matter. Make certain to handle file exceptions gracefully.
def countWord(name, word):
try:
f = open(name, "r")
lst = ([])
w = ""
for x in f.readlines():
w += x.lower()
lst = w.split()
f.close()
return lst.count(word)
except FileNotFoundError:
print("Please create a file or use the name of an existing text file.")

A friend a just opened his own barber shop and has asked you to develop a program to track the type of service the customer is receiving and the cost for the service and also include any tips the customer may give to the barber. The name of your friend's barber shop is Big Al's and on each customer receipt he wants to display the name of his shop, customer name, the type of service, cost of the service, and the amount of the tip for a total price of the service rendered. Name your variables Declare your variables
Answer:
class Barber(object):
barber_shop = "Big AI's barber shop"
def __init__(self, customer_name, type_of_service=[], tip=0):
self.cust_name = customer_name
self.tos = type_of_service
self.tip = tip
def service_type(self, *args):
for i in args:
self.tos.append(i)
def total(self):
services = {'trimming':10, 'hair_cut':20, 'shaving':15, 'washing':5, 'dyeing':5}
contain = ''
total = 0
for service in self.tos:
if service in services.keys():

f'total: ${total}', '\n',f'Tip: ${self.tip}')
mycust = Barber('John',['washing'],6 )
mycust.service_type('shaving', 'dyeing')

Explanation:
The Barber class is a blueprint used to create an object instance of customers that visits the barber-shop. It has two methods 'service_type' and 'total' which are just defined functions of the class that appends services to the type of service variable and total that prints the total cost of services on the screen.

(Java) Write a program that accepts a number of minutes and converts it both to hours and days. For example, 6000 minutes is 100.0 hours or 4.166666666666667 days.
The program is a sequential program, and it does not require any conditional statement or iteration.
The program in Java, where comments are used to explain each line is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
//This declares minutes as a double data type
double mins;
//This creates a Scanner object
Scanner input = new Scanner(System.in);
//This gets input for minutes
mins = input.nextDouble();
//This converts the minutes to hour and days, and also print them
System.out.println(mins/60+" hours or "+mins/1440+" days");
}
}
At the end of the program, the equivalent number of hours and number of days are printed.
