Question

How many times a wheel of radius 28cm must ratate to go 352m square​

Answer 1

Step-by-step explanation:

Let us consider a wheel A of radius 28 cm. Let us assume the number of rotations required by wheel A to cover 352 m distance be n. Therefore, 200 total rotations are required for the given wheel A to go 352 m.

Answer 2

Answer:

Let us consider a wheel A of radius 28 cm. Let us assume the number of rotations required by wheel A to cover 352 m distance be n. Therefore, 200 total rotations are required for the given wheel A to go 352 m.

Step-by-step explanation:

Let wheel must be rotate n times of its circumference.

Radius of wheel=28cm and Total distance=352m=35200cm

∴ Distance covered by wheel=n×circumference of wheel

⇒35200=n×2πr

⇒35200=n×2×

7

22

×28

⇒n=

2×22×28

35200×7

⇒n=200 revolutions.

Thus, wheel must rotate 200 times to go 352 m.
