Answer: approximately 25.13 centimeters.

Step-by-step explanation: If the diameter of a circle is 8cm, then the radius is half of that, which is 4cm. We can use this information to calculate the area and circumference of the circle as follows:

Area of circle = π * r^2

= π * 4^2

= π * 16

= 16π

≈ 50.27 cm^2 (rounded to two decimal places)

Circumference of circle = 2π * r

= 2π * 4

= 8π

≈ 25.13 cm (rounded to two decimal places)

Therefore, the area of the circle is approximately 50.27 square centimeters and the circumference is approximately 25.13 centimeters.
