[solved] – Question 8544
// Qs. Write java program that contains the following 2 classes.
(i) Circle class that contains a radius field and getArea method that calculates its area.Give it a constructor where u pass in the radius.
(ii) TestCircle class which creates an array of 100 circles, each with a a random radius and prints out the sum of the areas , the biggest & smallest areas
class Circle {
private float radius;
public Circle(float r)
{
this.radius=r;
}
public float getArea()
{
return (float)(Math.PI*radius*radius);
}
}
class circle7
{
public static void main(String[] args)
{
Circle circles[]= new Circle[100];
for(int i=0; i<circles.length; i++)
{
circles[i]= new Circle((float)(50*Math.random()));
showAreas(circles);
System.out.println(“the sum is”+ areaSum(circles));
System.out.println(“the minimum is”+ minArea(circles));
System.out.println(“the maximum is”+ maxArea(circles));
}
public static float areaSum(Circle c[])
{
float sum= 0;
for(int i=0; i<c.length; i++)
{
sum+= c[i].getArea();
}
return sum;
}
public static float minArea(Circle c[])
{
float min= c[0].getArea();
for(int i=1; i<c.length; i++)
{
if(c[i].getgetArea()<min)
min= c[i].getArea();
}
return min;
}
public static float maxArea(Circle c[])
{
float max= c[0].getArea();
for(int i=1; i<c.length; i++)
{
if(c[i].getgetArea()>max)
max= c[i].getArea();
}
return max;
}
public static void showAreas(Circle c[])
{
for(int i=0; i<c.length; i++)
{
System.out.println(c[i].getArea());
}
}

Create a Windows application that can be used as a sign-up sheet for ski equipment for the Flyers Sports Club. The club has ski equipment that it makes available to members at a minimal charge. In an attempt to determine what type of equipment members might need for an upcoming trip, they have asked you to design and implement an equipment-needs form. Include CheckBox objects that allow users to select the type of gear they will need to purchase for the trip. Include selections of snow gloves, skis, goggles, earmuffs, and other items you feel are appropriate. Include at least one picture

I’m trying to evaluate the limit :::::
Limit[(sqrt[t^2 + 9] – 3)/(t^2), t -> 0]
When i click “evaluate cell” Mathematica outputs :::::
!(*UnderscriptBox[([Limit]), (t [Rule] 0)]) (-3 +
sqrt[9 + t^2])/t^2
which is the same thing as what I typed in only in a slightly different order (essentially the same thing i typed in) what am i doing wrong ?
