Question

please solve this problem​

Answer 1

Answer:

circumference of wheel=2πr

=2.22/7.28=176cm=1.76m

No of rounds=352/1.76

=200 rounds

HOPE THIS HELPS

Answer 2

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× 722×28

⇒n= 2×22×2835200×7

⇒n=200 revolutions.

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