If a Ferris Wheel has a diameter of 80 meters, how far does a rider travel in one complete rotation around the wheel?

251.2 m

Step-by-step explanation:

Step 1:

The complete rotation in circular wheel is its circumference.

Circumference = 2 × 3.14 × r

where r = radius

Step 2:

Here 2r = d = 80m

Circumference = 80 × 3.14

                          = 251.2 m

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
