Question

How many time a wheel of radius 14 cm must rotate to go 528 m​

Answer 1

Answer:

Wheel must rotate 200 times 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 whee l= n x circumference of wheel

⇒ 35200 = n×2πr

⇒ 35200=n × 2 × 22/7 x 28

⇒ n = 35200×7 /2 x 28 x 22

⇒ n = 200 revolutions.

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