hiii!!!
here's ur answer...
and don't say this one also please, we r always ready to help u :D
now, come to ur question...
given diameter of the wheel is 70cm, therefore radius of the wheel = 70/2 = 35cm
circumference of the wheel = 2πr
= 2 × 22/7 × 35
= 44 × 5
= 220cm
in metres = 220/100 = 2.2m
we know that 1km = 1000m
therefore 99km = 1000 × 99 = 99000m
hence, no. of revolutions it will make to cover 99km = 99000/220
= 450
it will make 450 revolutions.
hope this helps u..!!

hey.. circumference is Πd
yes but also 2πr
thanks
mention not :)
in the 4th line from below you have taken 220 whcich should have been 2.2 bruh
yeah sorry
so the answer is 45000
yup

d = 70, r = 35
1 revo = circum = 2*pie*r
= 2*22/7*35
= 220 cm
dist = 99 km = 9900000 cm
no of revos = total dist / circum
= 9900000/220
= 45000
Hope this helps
