Question

find the number of revolution made by a circular wheel of are 6.16 m square in rolling a distance of 572m

Answer 1

Hey Friend,

Area = 6.16 m^2
$\pi$ x r^2 = 6.16
r^2 = 616 / 100 x 7 / 22
r^2 = 196 / 100
r = 14 / 10
r = 1.4 m

Circumference = 2 x $\pi$ x r
                        = 2 x 22/7 x 1.4
                        = 8.8 m

Distance = 572 m

Number of revolutions = Distance / Circumference
 made by the wheel     = 572 / 8.8 
                                     = 65

Therefore, the wheel makes 65 revolutions to cover 572 meter.

Hope it helps!
