for covering 88 km a wheel revolve 1000 times . what is the radius of wheel ?
distance travel in 1 round = 88000 / 1000 m = 88 m perimeter = 88 m , 2 π r = 882 r = [ 88 * 7 / 22 ] = 28 m hence , diameter = 28 m answer c
multiply(multiply(divide(divide(multiply(divide(88, 1000), add(const_3, const_4)), const_2), add(multiply(const_10, const_2), const_2)), const_1000), const_2)
