To draw the equation of a circle, you need the center coordinates 
and the radius 
.
Once you know them, you can write the equation for the circle as
We can eyeball the center coordinates: from the origin, we have to go one step right and two steps below, so the coordinates are 
For the radius, you can see that if you move three units up, down, left or right from the center, you reach the circumference. So, the radius is 3.
Given everything we said above, we're ready to write the equation:
Answer:
He or she has 232,840,800 beats in five minutes.
Step-by-step explanation:
This question is solved by proportions.
In this question:
A year has 365 days.
Each day has 24 hours.
Each hour has 60 minutes.
Minutes in five years:
5*365*24*60 = 2,628,000 minutes.
How many beats in five minutes?
88.6 beats/min, 2,628,000 minutes. So the number of bears is:
88.6*2628000 = 232,840,800
He or she has 232,840,800 beats in five minutes.
