Final answer:
To find the diameter of a circumference, divide the circumference by π to find the radius, then multiply the radius by 2 to find the diameter.
Step-by-step explanation:
The diameter of a circumference can be found by using the formula: d = 2r, where d is the diameter and r is the radius. Since the question mentions a circumference of 4.6 inches, we can divide it by π (approximately 3.14159) to find the radius. So, r = 4.6 / π. Finally, we can substitute this value of r into the formula to find the diameter: d = 2 * (4.6 / π).
