A bicycle wheel makes five rotations. The bicycle travels 40.56 ft. Find the diameter of the wheel in inches. Use 3.14 for π.

Answer 1

40.56 feet with 5 rotations of the bicycle wheel

what is the wheel's diameter in inches? use 3.14 = pi

40.56 feet = 40.56x12 = 486.72 inches

each rotation, the bike moved 486.72/5 = 97.344 inches

= the circumference of the bike wheel

= pi x the wheel's diameter

3.14d = 97.344

d = 97.344/3.14 = about 31.001

= about 31 inch diameter
