Question

Two bicycle wheels are shown below which is closest to the circumference in inches of the larger wheel.

Answer 1

We estimate the diameter of the larger wheel to be 24 to 25 inches.

The formula for the Circ. of a circle in terms of the diameter is C = pi*d.

Here, the Circ. of the larger wheel is approx C = pi(24 inches) = 24*pi inches,
or 

24(3.14) inches = 75.36 inches.   You must now choose from the four answer choices.  Which one is closes to 75.36 inches?
