Question 886240: Find the area of the walkway (24 inches wide) that will be installed around a circular jacuzzi with diameter of 6 feet.

Area of a circle is Pi r squared.
The area of the jacuzzi is Pi * 3 squared, or 9 Pi (diameter = twice the radius)
The area of the walkway is Pi * 4 squared (the diameter will be 8') less the area of the jacuzzi.
Pi * 4 squared = 16 Pi
16 Pi - 9 Pi = 7 Pi <<--area of the walkway
