How many times, correct to the nearest whole number, will a man run round circular track of diameter 100m to cover a distance of 1000m?
3
4
5
6
Explanation
No. of times = \(\frac{\text{Total distance}}{\text{Circumference of circle}}\)
= \(\frac{\text{Total distance}}{\pi d}\)
= \(\frac{1000m}{\frac{22}{7} \times 100m}\)
= \(\frac{1000 \times 7}{2200} = 3.187\)
= 3(approx.) nearest whole no.
= \(\frac{\text{Total distance}}{\pi d}\)
= \(\frac{1000m}{\frac{22}{7} \times 100m}\)
= \(\frac{1000 \times 7}{2200} = 3.187\)
= 3(approx.) nearest whole no.
