1.	A car travels 1 kilo meter distance in which each wheel makes 450 complete revolutions. Find the radius of its wheels.
Answer» Total distance covered = 1 km = 100000 cm Distance covered by circular wheel in 1 revolution = circumference of circle Circumference of circle = 2πr Total no. of revolution = 450 = 2πr × 450 = 100000 r = \(\frac{10000\times7}{450\times2\times22}\) = 35.35 cm

A car travels 1 kilo meter distance in which each wheel makes 450 complete revolutions. Find the radius of its wheels.

Answer»

Total distance covered = 1 km = 100000 cm

Distance covered by circular wheel in 1 revolution = circumference of circle

Circumference of circle = 2πr

Total no. of revolution = 450

= 2πr × 450 = 100000

r = \(\frac{10000\times7}{450\times2\times22}\) = 35.35 cm
