Explanation:
Given
Solving (a):
print(ex[0:2])
This prints the elements from 0 index to 2-1
In other words, it prints index 0 and 1
Hence, the output is [5, 3]
Solving (b):
ex.append(8) --> This adds 8 to the end of the list
print(ex) --> This prints the updated list: [5, 3, 0, 1, 2, 8]
Solving (c):
ex.remove(0) --> This removes 0 from the list
print(ex) --> This prints the updated list: [5, 3, 1, 2, 8]
Solving (d):
ex.pop() --> This removes the last ite, from the list
print(ex) --> This prints the updated list: [5, 3, 1, 2]

Explanation:
The following class is written in Java. I created the entire Circle class with each of the methods and constructor as requested. I also created a tester class to create a circle object and call some of the methods. The output can be seen in the attached picture below for the tester class.
class Circle {
double radius;
public Circle(double radius) {
this.radius = radius;
}
public double getRadius() {
return radius;
}
public void resetRadius() {
radius = 0;
}
public double calculateArea() {
double square = Math.pow((Math.PI * radius), 2);
return square;
}
}
