Circles
Area of Circle is 
Total percentage increase in the area of the modified circle is 69%
Explanation:
(a) Given the diameter of the circle be d
Then the radius of the circle = r = d/2
and the area of the circle is given by:
Area(A) = 
A = 
A =
The area of circle is
(b)
The increase in percentage while changing the dimensions is given by the formula :
Total % increase = a% + b% - (a% * b%)/100
Where ,
a% is the percentage increase in side a
b% is the percentage increase in side b
Let the percentage increase in radius is : a%
Since a% = b%
So the formula is
Total increase % = a% + a% + (a% * a%)/100
Given here the diameter of the circle increases by 30% so a =30
Therefore, putting the value of a in the formula
Total increase % = 30% + 30% + (30% *30%)/100
Total increase % = 60% + 9%
Total increase % =69%
Therefore the total percentage increase in the area of the modified circle is 69%
Answer:
True.
Explanation:
If a firm puts servers that are internet facing directly on the internet then the servers are exposed to external attacks and these attacks can be from anywhere in the world.

Answer:
The Java code is given below with appropriate comments as well as the sample output
Explanation:
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
System.out.println("Enter a date in the form mon/day/year:");
Scanner scanner = new Scanner(System.in);
String inputDate = scanner. nextLine();
//Split the string string with / as the delimiter
String[] dateComponents = inputDate.split("/");
//Rearrange the date and month part and join with '.' as sepertor
String outputDate = String.join(".", dateComponents[1], dateComponents[0], dateComponents[2]);
System.out.println("Your date in European form is:\n" + outputDate);
}
}
<u>Sample Output
</u>
Output 1:
Enter a date in the form mon/day/year:
01/22/2020
Your date in European form is:
22.01.2020
Output 2:
Enter a date in the form mon/day/year:
1/22/20
Your date in European form is:
22.1.20
Answer:
