The equation of a circle centered at (h, k) and with radius r is
In this case, the center is point (2, 1), so h = 2, and k = 1.
We also need the radius. We are not given the radius, but we have the center and a point on the circle. The distance between the center and any point on the circle is the radius. We can use the distance formula to find the distance between points (2, 1) and (5, 2).
The radius is the distance between the points, so
Now we have all the information we need, so we can write the equation of the circle.

Answer:
- 80 restaurant purchased meals are eaten in a restaurant
- 31 meals are eaten in a car
- 60 meals are eaten at home
Step-by-step explanation:
Let us suppose r be the total number of meals eaten in a restaurant
Let us suppose c be the total number of meals eaten in a car
Let us suppose h be the total number of meals eaten in a home
- The total number of meals eaten in a restaurant, in a car or at home is given as 163. Hence,
- The total number meals eaten in a car or at home exceeds the number eaten in a restaurant by 11. Hence,
- Twenty more restaurant-purchased meals will be eaten in a restaurant than at home. Hence,
Substituting Equation [B] into [A],
Putting in
Putting and in
Therefore,
- 80 restaurant purchased meals are eaten in a restaurant
- 31 meals are eaten in a car
- 60 meals are eaten at home
Verification:
Putting , and in
