Question

the radius of wheel of a car is 35cm how many revolutions will it make a distance of 550m​

Answer 1

Answer:

250 revolutions

Step-by-step explanation:

Step 1 : Find the circumference of the wheel :

C = 2πr = 2 x $\frac{22}{7}$ x 35 = 2 x 22 x 5 = 10 x 22 = 220 cm

Step 2 : Divide by total distance :

550 m = 550 x 100 cm = 55000 cm

Number of revolutions = $\frac{55000}{220}$ = $\frac{5500}{22}$ = $\frac{500}{2}$ = 250

∴ It will take 250 revolutions to make the distance of 550 m.
