Question

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

Answer 1

Answer:

mark me brainliest if it helps you

plzzzzzz

Step-by-step explanation:

So here, if the radius (R) = 28cm, the circumference (C) => 2πR = 2 x (22/7) x 28 = 176 cm.

The required distance (D) is 352 m = 352 x 100 cm [1m = 100cm].

Thus, the number of times the wheel must rotate

= Total Distance/Circumference

= D/C = 352 x 100/176 = 2 x 100 = 200.

Hope this helps ! :)
