Janet has a circular garden in her front yard with a diameter of 8 feet. How does the diameter d compare to the circumference C of the garden?
F) D = 1/3C
G) D = 1/2C
H) D = 2C
I) D = 3C

Math 
Anon,
Because diameter is twice the radius, the radius must be 1/2 of 8 ft. So r=4ft.
The circumference is equal to 2*pi*radius. Since pi is =3.14
Thus by comparing the two equations
D=2r
C=2rpi
the only difference is pi so the answer would be F if you assume 3.14 is approximately 3
