Question

The diameter of Ravi's bike is 29.4 cm. It makes 1200 revolution to reach his office from home. Find the distance of his office.​

Answer 1

Step-by-step explanation:

Here we have to find the circumference of the wheel and multiply it with the number of revolutions.

diameter = 29.4cm

radius = 29.4/2 = 14.7cm

Circumference = 2$\pi$r

                         = 2 * 22/7 ^ 14.7 = 2 * 22 * 2.1              (cancelling 7 and 14.7)

                         = 44*2.1

                         = 92.4cm

Number of revolutions = 1200

Distance of his office = 1200 * 92.4

                                   = 1,10,880cm

                                   = 1.1088km
