Explanation:
In this question
d is known as diameter
r is known as radius
c is known as circumference
pi is known as π
a is known as area
Now, In Maths
Area of circle = π×r×r
Circumference of circle = 2×π×r
Radius (r) = diameter(d)÷2
Given diameter is 6
then, r = 6 ÷2
r = 3
so, diameter = 6
radius = 3
circumference = 2×π×r
= 2×3.14×3 ( the value of π is equal to 3.14)
= 18.84
Area = π×r×r
= 3.14×3×3 ( the value of π is equal to 3.14)
= 28.26
Answer:
B - E-Mail
Explanation:
This is a program to create, send, receive, forward, store, print, and delete e-mail messages.
Answer:
import java.util.regex.*;
import java.util.Scanner;
public class Password
{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("Please enter the Password. \n");
String passwordString = input.next();
System.out.println(passwordCheck(passwordString));
}
public static boolean passwordCheck(String password){
if(password.length()>=8 && password.matches("[a-z0-9A-Z]+")){
return true;
}
else{
return false;
}
}
}
Explanation:
The Java class "Password" is used by the program to make an instance of the password object and check its validity with the passwordChecker method defined within the Password class. The passwordChecker method only matches alphanumeric passwords, that is, passwords with alphabets and numbers. If a non-alphanumeric character is encountered, the boolean value false is returned.
