Question

The number of revolutions made by a circular wheel of radius 0.7m in rolling a distance of 176m is ❓​

Answer 1

Answer:

40

Step-by-step explanation:

We know,

No. of revolutions=total distance /circumference

Circumference = 2 * 22/7 * 7/10

= 4.4 m

Number of revolutions = 176/4.4

= 40 revolutions...ans

Answer 2

given, radius =0.7 m

distance=176m

to find: no of revolutions=?

Step-by-step explanation:

As We know that,

"No. of revolutions=total distance /circumference"

Circumference =2πr= 2 * 22/7 * 7/10          [∴π=22/7 or 3.14]

 = 4.4 m

∴Number of revolutions = total distance/circumference

=176/4.4

= 40 Revolutions.

hence, the required no of  revolutions=40.
