1.	How many rounds does a wheel of radius 35 take in order to cover a distance of 880 metre? (π = 22/7).
Answer» Radius of wheel (r) = 35 m Circumference of wheel = 2πr = 2 x 22/7 x 35 = 2 x 22 x 5 = 44 x 5 = 220 m Wheel covers 220 metre distance revolution. So to cover a distance of 880 metre number of revolution = 880/220 = 4 revolution.

How many rounds does a wheel of radius 35 take in order to cover a distance of 880 metre? (π = 22/7).

Answer»

Radius of wheel (r) = 35 m

Circumference of wheel = 2πr

= 2 x 22/7 x 35

= 2 x 22 x 5

= 44 x 5

= 220 m

Wheel covers 220 metre distance revolution.

So to cover a distance of 880 metre number of revolution = 880/220 = 4 revolution.
