A circular garden is 7'4" in diameter. A geranium is planted every foot along the outside of the garden (circumference). How many geraniums are needed?

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.
