You can say that the center is an arbitrary point at (x0, y0)
The distance from each point to the center is the same
d^2 = (x-x0)^2 + (y-y0)^2
Plug in each point into this equation (plug into x and y) and you have a 3x3 system that you can solve for x0 y0 which is the center and d which is the radius. Then you have the equation by putting these constants into the above equation.
Answer:
33
Step-by-step explanation:
9 out of 30 employees want a watch
So the ratio is 9/30
So in 110 employees want a watch 110×9/30
=33
So 33 out of employees want a watch
2 because 93 only goes in to 100 once and you only have 253
The height of an oak tree (which depends on the age of the tree) is 100
