What is the length of the radius, r?

Option B. (x - h)² + (y - k)² = r²

Step-by-step explanation:

Equation of a circle which passes through a point P(x, y) and center at (0, 0) then the equation of the circle is represented by

x² + y² = r²

If center of the circle is moved from origin (0, 0) to (h, k) then we have to find the equation.

(x - h)² + (y - k)² = PQ² = r² [Distance between two points P and Q]

Therefore option B is the correct answer.

answer: the 4 kilogram bag

step-by-step explanation: this is because if you divide the number of kilograms into the total it will tell you how much each individual kilogram would be worth. 2 kilos is 7 and change 3 would be around 6 ish and the 4 kilo would be 4.6 and change and the 5 kilos would be like 4.88
