A large circular garden is surrounded by a stone wall that is 6 inches wide.
The circumference of the OUTSIDE of the stone wall measures 54 feet.
:
A. Find the radius of the garden INCLUDING the stone wall.
The equation: 2*pi*r = C
2*pi*r = 54
r =
r = 8.6 ft is the radius including the wall
:
B. Find the radius of the garden WITHOUT the stone wall.
6 inches = .5 ft
8.6 - .5 = 8.1 ft radius inside the stone wall
:
C. Find the area of the garden (not including the stone wall) in square feet.
A = pi*8.1^2
A = 206.12 sq/ft, area inside the stone wall
