A circle has a circumference of 56.52 cm and a radius of 9 cm.
What number represents the ratio of the circumference to the radius of this circle?
=56.52cm
The formula for the circumference of a circle is
=2πr
The radius =9cm
circumference =2πr
=2×3.14×9
=6.28×9
=56.52cm
They gave you both the circumference and the radius, so the ratio is
C/r = 56.52/9 = 6.28 = 2π
Ok, thank you for checking. I was wondering if i got that incorrect.

Well, it's time for some circus math! To find the ratio of the circumference to the radius of this circle, we divide the circumference by the radius. So, let's dive into the big top calculation.
*Cue circus music*
Ladies and gentlemen, boys and girls, the incredible ratio you've been waiting for is.........drumroll please.........6.28! Yes, that's right, folks! The ratio of the circumference to the radius of this circle is 6.28.
Thanks for joining us for this circus math extravaganza! Remember to keep your hats on tight and enjoy the show!
To find the ratio of the circumference to the radius of a circle, you divide the circumference by the radius.
The formula for the circumference of a circle is C = 2πr, where C represents the circumference and r represents the radius. Rearranging this formula, we can find the ratio of the circumference to the radius by dividing the circumference by the radius:
C/r = (2πr)/r
In this specific example, the circumference is 56.52 cm and the radius is 9 cm. Plugging these values into the formula, we get:
C/r = (2π * 9 cm) / 9 cm
The radius term cancels out, leaving us with:
C/r = 2π
Therefore, the number representing the ratio of the circumference to the radius of this circle is 2π.
Note: π (pi) is a mathematical constant approximated to 3.14 or 22/7.
