First: Equations are solved. 
is an expression, and expressions can be simplified.
Now suppose 
. Imagine a right triangle with one angle (not the one opposite the hypotenuse, of course) labeled 
. This relation suggests that
and under the hood, we're assuming that 
, because otherwise we wouldn't be able to properly alternate from 
to so seamlessly.
Now,
so the given expression is the same as the tangent of that same angle .
If , then in the triangle, the leg opposite the angle occurs with the length of the hypotenuse in a ratio of to 2. By the Pythagorean theorem, the remaining side - call it 
- satisifies
and we have

Hi there!
• Radius =
ft = 5 ft.
Area of the fountain = πr² = 3.14 x (5)² = 78.5 ft²
•Radius for fountain n' walk =
=
= 6.5 ft
Area of fountain n' walk = πr² = 3.14 x (6.5)² = 132. 6 ft²
| Area of th' Circular walk |
132.6 - 78.5 ft² = 54. 1 ft²
ar( Larger circle ) - ar( Smaller circle )
Hence,
The area of the walk around the fountain is 54. 1 ft²
~ Hope it helps!
