The wheels on Annie's bicycle are 20 inches in diameter. If each wheel makes 3 full revolutions every second, then how many feet does Annie travel in 1 second? Give your answer as an integer, rounded to the nearest foot.

Circumference = Diameter x Pi

Circumference = 20/12 x 3.141592

Circumference =5.236 ft. Circumference of the wheel.

5.236 x 3 =15.708 ft. =~16 feet per second.

thx that was correct.
