The solution is the interval ------> (-∞, 45/41)
All real numbers less than 45/41
In a number line , the solution is the shaded area at left of x=45/41 (open circle)
The graph in the attached figure
With a 20 ft leash, the dog can move in the circle. Now, knowing that he can move around in a circle, we just need to use the circle formula. A = 3.14(r) squared.
Since you use 3.14 for pi; A = 3.14(20) squared --> A = 1256
Answer = 1256
The answer is 180
