$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
