Answer 2

The diameter of the wheel is 0.77 m

Step-by-step explanation:

Distance traveled in 50000 revolutions = 121 km =121000 m

Distance traveled in 1 revolution =$\frac{121000}{50000}=2.42 m$

Circumference of wheel =$2 \pi r = 2 \times \frac{22}{7} \times r$

So, $2 \times \frac{22}{7} \times r =2.42$

$r=\frac{2.42 \times 7}{22 \times 2}$

r=0.385

Diameter = 2r =2(0.385)=0.77 m

Hence the diameter of the wheel is 0.77 m
