SOLUTION IS
WE KNOW STANDARD EQUATION OF CIRCLE^{2}](https://tex.z-dn.net/?f=%5Btex%5D%28X-a%29%5E%7B2%7D)
+
=
where (a,b) is centre and r is radius of circle
now we have to find component of centre and radius
we know centre of circle is equidistance from end points of diameter
apply formula to find mid point of line( (x1+x2)/2,(y1+y2)/2) we get
((x-x)/2,(y-y)/2)=(0,0)
hence component of circle is (0,0)
now apply distance formula between (0,0)and (x,y)
we get 
+
=
hence standard equation of circlre is =
+
=+

Answer:
the graph
Step-by-step explanation:
Answer:
$40 / x ; $10 / y
Step-by-step explanation:
1.)
For the question, the number of girls aren't given ;
Assume the number of girls = x
The total amount they agreed to spend between themselves = $40
Amount spent on average :
Total amout to be spent / number of girls
Amount spent on average by each girl = $40 / x
2.)
The cost of ice cream isnt given;
Assume, cost per ice cream $y
Amount to be spent on on ice-cream = $10
Number of ice creams that can be purchased :
Amount to be spent on ice-cream / cost per ice cream
$10 / y
