Question

Given a circle with a diameter of 8, which equation expresses π as the ratio of the circumference of a circle to its diameter? Answer choices are in the picture

Answer 1

i cant see the picture since it was a pop up on my screen if you get me :,)

anyways, i used an approximation of pi, 3.14

to find circumference you either use the one for radius (3.14x2xr) or diameter (3.14xD)

so it was just 3.14 times 8, getting me 25.12. hopes this helps!
