The circumference of a circle can be calculated using the formula: C = 2 * π * r, where r is the radius of the circle.

Given that the radius is 9.5 cm, we have:

C = 2 * 3.14 * 9.5
C = 59.6 cm

To the nearest tenth, the circumference of the circle is 59.6 cm. Therefore, the closest response is:

B 59.7 cm

The ratio of the circumference of a circle to its diameter can be found using the formula:

C = πd

Given that the radius is 10, the diameter would be 2 * 10 = 20.

So the equation that expresses the ratio of the circumference of the circle to its diameter is:

C/20 = π

Therefore, the answer is:

B C/20 = π

The formula for the circumference of a circle in terms of its diameter is:

C = πd

Given that the diameter is 8, the formula for the circumference is:

C = π * 8

The equation expressing π as the ratio of the circumference to the diameter is:

C/8 = π

Therefore, the answer is:

B C/8 = π
