Answer:
public static double areaSum(Circle c1, Circle c2){
double c1Radius = c1.getRadius();
double c2Radius = c2.getRadius();
return Math.PI * (Math.pow(c1Radius, 2) + Math.pow(c2Radius, 2));
public static void main(String[] args){
Circle c1 = new Circle(6.0);
Circle c2 = new Circle(8.0);
areaSum(c1,c2);
}

Answer:
B. Replace the Bluetooth headset with a new pair.
Explanation:
Since all other mobile devices, after receiving the "corporate-wide" OS update, aren't having issues with pairing with Bluetooth headsets, we can safely conclude that the OS update isn't the issue.
To find out if the Bluetooth headset is not the culprit, we can try to pair the mobile device with a different headset. If it pairs correctly, then we can conclude that the old Bluetooth headset might have a fault, or it might need to be disconnected/forget from the device and paired gain.
Answer: Concurrent programs are the programs that execute at the same point of time. They are simultaneous in nature with other concurrent programs.They are executed with the help of threads to achieve the concurrency without the issue of scheduling. They are consider long running programs.
The program that has the low execution time compared with all other programs gets executed first.If the case of no progress is seen then another thread is executed.This type of execution gives the non- deterministic situation in which the possibility of leading completion of any particular program cannot be determined.
Answer:
True
Explanation:
The advent of personal computing brought about by the implementation of several technologies including MOSFET, semiconductors, microchip and integrated circuits has revolutionized life in at a very high rate of change where traditional ways of doing things rapidly change and for the first time power was easily reachable by accessing a personal computer.
1. The computer personal computer brought about word processing, where there are very limited errors in individually printed documents and the time to produce a quality document was reduced
2. Email - With the advent of personal computers email, the information and communication time were lowered and it resulted in changes in commerce
3. Video conferencing - It was possible to have video conferencing with people and make decisions regarding direction can be made real time from very distant locations, which improved business reaction time
4. The mouse- The concept of having a graphic user interface improved computer interaction for people with limited programming skills.
