The standard equation for a circle with center at (h,k) and radius r is
(x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center of the circle.
The formula for the circumference of a circle is C = 2pi*r. In this particular problem, we need to determine the radius of the circle. That radius is: r = C/[2pi]. Here, C = 22pi, so we get r = 22pi/[2pi], and so r^2 = 11^2.
Putting to use the given info, we have:
(x+14)^2 + (y-5)^2 = 11^2

Answer:
- Grayson had 10 inches of snow in his lawn
- the snow falls at a constant rate of 0.5 inches per hour
- no snow was melting
- the snow has fallen for 3 hours
Let y be the height of the snow in the lawn
Grayson had 10 inches at the beginning (at t=0) so y= 10
3 hours passed so y= 10 + 3*0.5 = 11.5 inches
Grayson had 11.5 inches after three hours
Assuming that the snow continued to fall for an unkhown time t
y = 0.5*t + 10
we had 10 at the beginning so we add 10 (+10)
the snow is growing by 0.5 inches in the single hour so we multiply by 0.5
t is the time and it can 4, 5, 6 ...... hours
Just like a function :
- 0.5 is the slope
- t is the variable
- 10 is the y-intercept
The unit rate is 3 strike in 1 inning.
