$100 Question from Circle Equations
What is the equation of a circle whose center is at (3, 5) and radius is 9?
$100 Answer from Circle Equations
(x – 3)2 + (y – 5)2 =81
$200 Question from Circle Equations
What is the equation of a circle whose center is at (5, -9) and radius is 12?
$200 Answer from Circle Equations
(x – 5)2 + (y + 9)2 = 144
$300 Question from Circle Equations
Where does the point (2, 3) lie in relation to the circle centered at (3, -4) with a radius of 9 units?
$300 Answer from Circle Equations
On the interior.
$400 Question from Circle Equations
How do you find the scale factor between two circles, A and ʘBʘ ?
$400 Answer from Circle Equations
Radius Aʘ Circumference Aʘ------------- or -----------------------Radius BʘCircumference BʘWhat does this tell us?
$500 Question from Circle Equations
Where does the point (0,5) lie in relation to the circle centered at the origin and containing the point (3,4)?
$500 Answer from Circle Equations
x2 + y2 = r2
32 + 42 = r2
25 = r2
5 = r
x2 + y2 = 2502 + 52 ?=? 2525 ?=? 25 Interior
