The diameter of a wheel is 0.7 m. How far will it travel in 200 revolutions Pick
A) 4.4 m  B) 220 m  C) 440 m  D) 560  E) 650

Rationale: diameter ( d ) = 0.7 m circumference of the wheel , = 2 * pi * r = d * pi = 0.7 * 3.14 = 2.198 m . in one revolution , wheel will covered = 2.198 m , so , in 200 revolution , it will cover = 200 * 2.198 = 4.396 m = 440 m ( approx ) . answer : option c
Answer: C
