Question

the diameter of a wheel of a car is 63 cm . how much distance will the car move in 2000 revolutions of the wheel.

Answer 1

Diameter = 63 cm

Radius = 63/2 = 31.5 cm

Circumference of Wheel = 2 x Pi x Radius

Circumference of Wheel = 2 x 22/7 x 31.5

Circumference of Wheel = 2 x 99

Circumference of Wheel = 198 cm

Therefore, I Revolution = 198 cm

Therefore 2000 Revolutions = 198  x 2000 = 396000 cm

Therefore the Car Travels 396000 cm or 3960 m or 3.96 km in 2000 Revolutions

Answer 2

Answer:

Step-by-step explanation:

Distance covered in 1 revolution= 2πr (Circumference)(Here,r stands for radius=d/2=63/2,d=diameter)

Distance covered in 1 revolution=2×22/7×63/2 (Circumference)

=198cm

Distance covered in 2000 revolutions=198×2000

=396000cm

=(396000/100)m

=3960m → Answer

Hope this explanation was satisfactory.....pls mark this as brainliest if it is so
