Answer:

Step-by-step explanation:
Given a circle centred at the point P(-4,-6) and passing through the point
R(2,2).
To find its equation, we follow these steps.
Step 1: Determine its radius, r using the distance formula
For point P(-4,-6) and R(2,2)

Step 2: Determine the equation
The general form of the equation of a circle passing through point (h,k) with a radius of r is given as: 
Centre,(h,k)=P(-4,-6)
r=10
Therefore, the equation of the circle is:

Answer: 54%
Step-by-step explanation:
24+17+5=46
100-46=54
Answer:
x² + y² = 4
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ← r is the radius]Here r = 2, thus
x² + y² = 4
Answer:
she walked another 2 miles.
Step-by-step explanation:
The answer is 17 1/4...but you probably can’t have 1/4 of a pie, so Mat can make a total of 17 pies
