Answer:
The area of the sidewalk is 144.44 m².
The 2-m wide walk adds 4 m to the diameter, making it 21+4=25.
Since the radius is half the diameter, r = 25/2 = 12.5.
The area of the entire bed with walkway is 3.14(12.5)² = 490.625 m².
The diameter of the bed is 21, so the radius is 21/2 = 10.5.
The area of just the flower bed is 3.14(10.5)² = 346.185.
The difference between the two is 490.625-346.185 = 144.44 m². This is the area of the walkway.

Answer:

Step-by-step explanation:
Let
x -----> the number of ice cream cones sold 5 years ago
Remember that

we know that
Sales 5 years ago, multiplied by the 30% increase should equal 18,000 ice cream cones.
so
The linear equation that represent this problem is

Solve for x
Divide by 1.3 both sides
