Question

The diameter of the wheel of a cycle is 70 cm. Find the distance covered by the wheel in 24 complete revolutions.

• A. 5820 cm
• B. 5280 cm
• C. 5028 cm
• D. 5082 cm

Answer 1

The correct option is B 5280 cm

Radius of the wheel $=\frac{70}{2}=35cm$
Distance covered by the wheel in one revolution is equal to its circumference.
$\therefore 2\pi r=2\times \frac{22}{7}\times 35=220cm$
Distance covered by the wheel in 24 revolutions
$=24\times 220=5280cm$
