Question

How many times a wheel of radius 35cm must rotate to go 286m²​

Answer 1

Answer:

It is given that the radius is 35.

so.. circumference is 2πr

=2×22/7×35

=2×110=220cm.

To go 286 m² ..

It will be 286×100 =2860000/220=286000/22

=13000

So, the wheel must rotate 13000 times to go 286cm².
