A. Find the radius of the garden INCLUDING the stone wall.
B. Find the radius of the garden WITHOUT the stone wass.
C. Find the area of teh garden (not including the stone wall) in square feet.
I can find the answer to A. 27ft/Pie
I think the answer to B is 26ft/Pie

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 = 54%2F%282%2Api%29
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
