Question

What is the distance covered by a wheel of radius 28 cm in 1 rotation?

• A. 22 cm
• B. 44 cm
• C. 88 cm
• D. 176 cm

Answer 1

The correct option is C 88 cm

The distance covered by a wheel in 1 rotation is equal to the circumference of the circle
Circumference of circle is given by $2\pi \times r$
Here the radius of circle 'r' is equal to 28 cm
So, circumference is equal to $\frac{22}{7}\times 28\times 2$ = 176 cm
The distance covered in one rotation = 176 cm
