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
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 radius of a circle is 10. Using π, which equation expresses the ratio of the circumference of the circle to the circle's diameter?
Responses
A
= πC 10 = π
B
= πC 20 = π
C C =
π
C = 10 π r
D C =

Responses
A
= πC 10 = π
B

C C =
π
C = 10 π r
D C =
π
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
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
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
