Answer:

Step-by-step explanation:
General Equation of circle is
----------- (1)
Here

Radius r is distance from origin (x1, y1) to point (x2, y2)=(-3, -6)




Substituting values in equation (1)


To Solve this, you need to take 3 the number awarded for correct, and multiply that by 12 the number of correct. Which gets you 36. Then yoou need to find the difference between20 and 36 which gives 16. Then youu need to divide that by 2 to get your ansewr of 8 in 1. Follow the same procces for ii.

1 ton=2000lb
total weight=2000
we want total weight=weight of cans
weight of cans=weight of 1 can times number of cans
W of cans=1/25c
total weight=weight of cans
2000=1/25c
times 25/1 both sides
50000=c
50,000 cans
