Question

how many times a wheel of radius 28 cm must rotate to go 176m take pie=22/7

Answer 1

Hey mate here is your answer

Answer:

100 times

Step-by-step explanation:

Given radius = 28cm

area of the wheel(as it is a circle)=2πr

                                                      =2×(22/7)×28=176cm  

as it must rotate 176m which is given meter's we need to convert it in cm

                                     17600

hence no of time it rotates=17600÷176 = 100 times

Hope it helped you :)
