You are welcome.
To find the circumference of a circle, you can use the formula C = 2πr, where C represents the circumference and r represents the radius of the circle.
Given that the radius of the circle is 3.5 cm, you can substitute this value into the formula to find the circumference.
C = 2π(3.5)
C ≈ 6.28(3.5)
C ≈ 21.98 cm
Rounding to the nearest tenth, the circumference is approximately 22.0 cm.
Therefore, the correct answer is A.
