A wheel covers a distance of 1,100 cm in one round. The diameter of the wheel is:
Answer & explanation
Correct answer: option 1
We know that,
Distance covered in one round = perimeter of the circle
2πr = 1100
= 2 × \(\frac{22}{7}\) × r = 1100
= r = 1100 × \(\frac{7}{22}\) × \(\frac{1}{2}\)
= r = 175 cm
Diameter of the wheel = 2 × 175 = 350 cm
