Question

how many times a wheel of radius 7m must rotate to cover a distace of 396m (take pie as=227) pls tell fast its very urgent...

Answer 1

Answer:

9

Step-by-step explanation:

In one rotation, the wheel covers a distance equal to its circumference.

C = 2*pi*r = 2 x 22/7 x 7

C = 44 m

For the given distance,

No. of rotations = 396/44 = 9

Answer 2

Answer:

Number of times a wheel must rotate to cover a distance of 396m

= 396/2πr

= 396/2×22/7×7

= 396/44

= 9m
