Question

if the radius of the wheel of a bus is 0.14 m how many rotations will a wheel complete while travilling a distance of 22 km​

Answer 1

Answer:

Step-by-step explanation:

circumference of wheel= 2πr

                                   

= (2 x0.14)π  = 0.88 m

no.of revolutions = distance travelled / circumference of wheel

                         

 = 22000/0.88

                         

 = 25000 revolutions

Answer ....

Answer 2

radius =0.14m

0.14*100=14 cm

circumferance=2pie r

2*22/7*14

=88 cm

no. of rotation =88*22
