Aprroximately ##1909.12 ” meters”.##
To find the distance around a circle, you need to find the circumference. The formula is ##C = dpi## This means that the circumference is equal to the diameter times ##pi##. The approximate value for ##pi## is ##3.14##, although it’s an irrational, never ending number.
The Ferris wheel has a diameter of ##76 ” meters”##. We can plug that into our formula along with the ##3.14## for ##pi##. Our formula is ##C=76 *3.14##. We can do the simple math and return that ##C = 238.64##. That means that this Ferris wheel is ##238.64 ” meters”##.
Now that we know the distance around the circle, we simply multiple by ##8##. ##8 * 238.64 = 1909.12##.
We can conclude that 8 turns of the this Ferris wheel would take you approximately ##1909.12 ” meters.”##
