Answer :
Final answer:
The number of geraniums needed is equal to the circumference of the circular garden, which is approximately 23 feet. Thus, about 23 geraniums would be needed.
Explanation:
To determine how many geraniums are needed, we first need to find the circumference of the circular garden. The formula for the circumference of a circle is C = πD, where D is the diameter of the circle. In this case, the diameter is 7'4" or 7.33 feet (since 4 inches is approximately 0.33 feet).
Therefore, the circumference of the garden is C = π * 7.33. After calculating, we find that the circumference is approximately 23 feet.
Because a geranium is planted every foot along the outside, we would need about 23 geraniums.
