A Ferris wheel travels around at a rate of 25 m/min and takes 19 min to do a full revolution. What is the radius of the Ferris wheel?

After 19 min of spinning, the Ferris wheel completes one revolution, so any fixed point on the wheel returns to the position at which it started. This point would cover a distance equal to the circumference of the wheel, equal to 2π times the radius r of the wheel.

This means the circumference of the wheel is

(25 m/min) * (19 min) = 475 m

and so the radius of the wheel is

(475 m) / (2π) = r = 75.59 m

which most closely matches D.

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

we can't see all full 4 options, but if this is the full option, than the very left one is correct:

-2/5 * -3 3/4

remake the question, adding a picture of all the question, or write down the full left and right answers.
