bicycle wheel makes 5000 revolution in moving 11 km. find the diameter of the wheel.
:
Find the number of meters in 11 km, divide by 5000
%2811%2A1000%29%2F5000 = 2.2 m, is the circumference of the wheel
pi%2Ad+=+2.2
:
d = 2.2%2Fpi
d = .7 meters or 70 cm is the diameter of the wheel
;
:
Check this by finding how far the you go in 5000 rev
%285000%2Api%2A.7%29%2F1000 = 10.99 ~ 11 km
