Answer:

Sure! Here are the solutions:

1. d = 17 cm

radius = 17/2 cm = 8.5 cm

circumference = π x diameter = 22/7 x 17 cm = 53.43 cm

solution: The circumference of the circle is 53.43 centimeters.

2. d = 13cm

radius = 13/2 cm = 6.5 cm

circumference = π x diameter = 22/7 x 13 cm = 40.84 cm

solution: The circumference of the circle is 40.84 centimeters.

3) r = 6.15cm

diameter = 2 x radius = 2 x 6.15 cm = 12.3 cm

circumference = π x diameter = 22/7 x 12.3 cm = 38.57 cm

solution: The circumference of the circle is 38.57 centimeters.

4. d = 8.5cm

radius = 8.5/2 cm = 4.25 cm

circumference = π x diameter = 22/7 x 8.5 cm = 26.71 cm

solution: The circumference of the circle is 26.71 centimeters.

5) r = 2.25cm

diameter = 2 x radius = 2 x 2.25 cm=4.5cm

circumference=π×diameter=22/7×4.5cm=14.14cm

solution: The circumference of the circle is **14.14 centimeters**.
