Answer: 25.461 cm

Explanation:

The circumference of a circle can be found using the formula C = πd, where d is the diameter and π (pi) is a constant value of approximately 3.14159.

Substituting d = 8.1 cm into the formula, we get:

C = πd

C = 3.14159 x 8.1 cm

C = 25.461 cm (rounded to 3 significant figures)

Therefore, the circumference of the circle with diameter 8.1 cm is approximately 25.461 cm.
