The equation of the circle whose center is at (2, 1) and radius is 3 is
a. (x + 2)² + (y + 1)² = 9
b.(x - 2)² + (y - 1)² = 9
c.(x - 2)² + (y - 1)² = 3

B.  (x - 2)^2 + (y - 1)^2 = 9.

Step-by-step explanation:

The general equation for a circle can be written as:

(x - a)^2 + (y - b)^2 = r^2    where the centre is at (a, b) and the radius= r.

Here a = 2, b = 1 and r = 3 so the answer is:

(x - 2)^2 + (y - 1)^2 = 3^2

= (x - 2)^2 + (y - 1)^2 = 9.

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
