Answer is A) 7
22/7= 3.1428571 pi
Radius (r) = 5”
Circumference formula: c= 2 x pi x r
Thus: c = 2 x 3.1428571 x 5 = 31.428571” which is also 1 revolution
Wheelbarrow travel rate = 55”/min
Duration traveled is 4 min, therefore 55” x 4 = 220” traveled in 4 min
Revolutions by wheelbarrow in 4 mins is as follows: 220” / 31.428571” = 7
