Hi there!

• Radius = \dfrac{10}{2} ft = 5 ft.

Area of the fountain = πr² = 3.14 x (5)² = 78.5 ft²

•Radius for fountain n' walk = \dfrac{10 + 3}{2} = \dfrac{13}{2} = 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!

kirill [66]
The correct answer for the problem above is -23 .

Explanation

1. collect the like terms

2x + x - 11 + 3 - 7x = 15
2x , x , & -7x are like terms
-11 & 3 are like terms

2x + x -7x = -4x
-11 + 3 = -8

2. Move constant to the right-hand side and change its sign .

-4x = 15 + 8
-4x = 23

3. Make the signs on both sides of the equation

-4x = 23 turning into 4x = -23

answer =

4x = -23
