Question

The distance covered in 10 revolutions by a wheel of radius 2.1 m is​

Answer 1

Step-by-step explanation:

to find this, we need to find the circumference:

Circumference=2πr

=2×3.14×2.1

=13.178×(no. of revolutions)

=13.178×10

=131.78m

Answer 2

Answer:

42m

Step-by-step explanation:

radius is 2.1 m,

so diameter will be - 2.1*2-4.2m

distance covered by the wheel in 10 revolutions will be - 10*4.2

which is 42 m (ans)
