Final answer:
To estimate the circumference of a circle with a diameter of 4.50 cm, multiply the diameter by Pi (approximately 3.14), resulting in an estimated circumference of approximately 14.13 centimeters.
Step-by-step explanation:
You have asked how to visually estimate the circumference of a circle when the diameter is 4.50 cm. To do this, you can use the mathematical relationship between the diameter and the circumference of a circle, which is the circumference is equal to π times the diameter (C = πd).
Since π (Pi) is approximately equal to 3.14, you can simply multiply the diameter by this number to get an estimate for the circumference. So, for a circle with a 4.50 cm diameter, the estimated circumference would be:
C = π × 4.50 cm
C ≈ 3.14 × 4.50 cm
C ≈ 14.13 cm
This estimation gives us a circumference of approximately 14.13 centimeters.
