Answer:
The code for this class is shown in the explanation section
Explanation:
public class Circle {
private double radius;
private double diameter;
private double area;
public Circle(double radius, double diameter, double area) {
this.radius = 1;
this.diameter = diameter;
this.area = area;
}
public void setRadius(double radius) {
this.radius = radius;
diameter = radius*2;
area= Math.PI*(radius*radius);
}
public double getRadius() {
return radius;
}
}
Answer:
Encryption
Explanation:
Encryption is a term in the field of computer security (Cryptology) this is a process of encoding information in a way that hackers and eavesdroppers cannot read. The process of encryption involves a plain text (message) been converted into a scrambled text (cipher text) with an encryption algorithm (key) in this way, if the message is intercepted by a hacker he/she is unable to read the contents. Only the authorized party with a decryption key will be able to decrypt back to a plain text and read the contents of the message

This was really useful in determining one's location during the times when technology wasn't that advanced yet. First is that it depends as to what time of the day is it being used. If used at day, most probably at high noon, the altitude of the sun would be measured and recorded and/or remembered. Most of the times, the latitude is determined during the day since it is much easier. At night, a star of known declination will be substituted to the sun. Most of the times, the North Star is used. Then, an almanac will be utilized to determine the declination of the Sun or the star, depending on which was used. After which, the formula is applied, which is latitude = 90 degrees - measured altitude +declination.
