The square footage of mulch that would be needed is 707 ft²
Circle is the locus of a point such that it distance from a fixed point is always constant.
The area (A) of a circle is given by:
A = πr²
Where r is the radius of the circle.
Given that the dog leash is 15 feet, hence:
radius = 15 feet
A = πr² = π(15)² = 707 ft²
