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
Surely you long ago learned that C=pi*d
pi is about 3, so using that, C=3d. Or, d = 1/3 C
To compare the diameter (d) to the circumference (C) of a circular garden, we need to know the relationship between the two measurements.
The formula to calculate the circumference of a circle is C = πd, where C represents the circumference and d represents the diameter.
To determine how the diameter compares to the circumference, we can rearrange the formula as d = C/π.
Comparing this rearranged formula to the given options:
f) d = 1/3C
g) d = 1/2C
h) d = 2C
i) d = 3C
We can see that the correct option is g) d = 1/2C.
