Sammy has a vegetable garden in the shape of a semicircle. If the diameter of the garden is 10 feet, what is the circumference of his garden?
The circumference of a circle is calculated using the formula C = πd, where d is the diameter of the circle. In this case, the diameter is 10 feet.
C = π x 10 feet
C ≈ 31.4 feet
Therefore, the circumference of Sammy's garden is approximately 31.4 feet.
