Question

the diameter of a wheel is 1.26 M how far will it travel in 500 revolution

Answer 1

Dimensions of Wheel -

Diameter = 1.26 m

Radius = (1.26 / 2) m = 0.63 m = 630 cm

Circumference of the Wheel -

= 2Πr
= [ 2 × 22 / 7 × 630 ] cm
= [ 2 × 22 × 90 ] cm
= 3960 cm

Total revolutions by the wheel = 500

∴ Total distance travelled by the wheel

= No. of revolutions × circumference of wheel
= [ 500 × 3960 ] cm
= 1,980,000 cm
= 19,800 m

Hence, the total distance travelled by the wheel is 19,800 meters.
