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
Answer:
Well, since there are four options, and Jamal is likely to pick any of them, 25% is the answer. 25 is also 1/4.

15% off
15% off of 50
notice that 50 is 1/2 of hundred
15% of 100 is 15
therefor
15% of 50 is 15/2=7.5
that is discount
50-7.5=42.5
new price=$42.5
