A circular fountain 10 feet in diameter has a circular walk 3 feet wide paved around it. What is the area of the walk?

Solution:

Diameter of a circle fountain = 10 feet

Radius of a circle fountain = 10/2

= 5 feet

We know that

Area of the fountain = πr²

 = 3.14 x (5)²

= 78.5 ft²

Radius of the fountain n’ walk = (10 + 3)/2

= 13/2

= 6.5 feet

Area of the fountain n’ walk = πr²

= 3.14 x (6.5)² = 132. 6 ft²

Area of the circular walk = area (Larger circle) - area (Smaller circle)

Substituting the values

= 132.6 - 78.5

= 54.1 ft²

Therefore, the area of the walk is 54.1 ft².
