The radius of a circle is 15. Using π, which equation expresses the ratio of the circumference to the diameter of a circle?
Kobotan [32]

Answer:

The equation which expresses the ratio of the circumference to the diameter of a circle is  \frac{C}{30}=\pi ⇒ D

Step-by-step explanation:

π is the ratio between the circumference of the circle and the length of its diameter

\frac{C}{d}=\pi , where

  • C is the circumference of the circle
  • d is the diameter of the circle

∵ The circumference of the circle is C

∵ The radius of the circle is 15 units

∴ r = 15 units

- Find the diameter of the circle

∵ The diameter of the circle d = 2 r

∴ d = 2(15) = 30 units

∴ The diameter of the circle is 30 units

∵ \frac{C}{d}=\pi

∵ d = 30 units

∴ \frac{C}{30}=\pi

The equation which expresses the ratio of the circumference to the diameter of a circle is  \frac{C}{30}=\pi
