The radius of a circular wheel of a toy car is 56 mm. In how many revolutions can it cover a distance of 176 cm? [Use π = $\frac{22}{7}$]

5

We know that,

Distance covered in one revolution = 2πr

Radius of a wheel of a toy car = 56 mm.

Distance covered in one revolution = 2 × \(\frac{22}{7}\) × 56 = 352mm

We have,

Total distance covered = 176 cm = 1760 mm

Number of revolutions he makes = \(\frac{1760}{352 }\) = 5
