Question

A car wheel has a diameter 60 cm.
How many times will the wheel rotate to cover a distance of 500 m²
Give your answer correct to the nearest whole number.
i.264 times
ii.263 times
iii.266 times
iv. 265 times
​

Answer 1

(IV) 265 times

Step-by-step explanation:

diameter = 60cm

radius =30cm

in one rotation it covers a distance= circumference of wheel

so

in one rotation distance covered = 2×π×r

therefore

number of times the wheel rotate = 500/distance in 1 rev

=500/2×3.14×0.3=500/1.884=265.39
