The formula to calculate the circumference of a circle is C = 2πr, where r is the radius of the circle.
Given that the radius of the photo frame is 8 cm, we can substitute this value into the formula:
C = 2 x π x 8 cm
C = 16π cm
Using an approximate value of π = 3.14, we can calculate the circumference:
C ≈ 16 x 3.14 cm
C ≈ 50.24 cm
Therefore, the circumference of the round photo frame is approximately 50.24 cm.
