Circumference = 2πr
So the circumference of the track is C = 2π .2 or .4π
3 times around the track is .4π x 3 or 1.2π - this is the answer but most teachers will want you to use 3.14 for pi.
so 1.2 x 3.14 = 3.768 km
Do you notice that I waited until the end to use the actual value of pi (3.14) in my calculations.
Keeping things in pi units until the very end saves time.
Answer:
117
Step-by-step explanation:
since it's exactly 93.6%, it means it must be more than 100people as it can't be 93.6people/100people as a person cannot be less than 1. the lowest possible number of people therefore can only be 117/125people as when converted to a fraction, 93.6% = 93.6/100 but no decimals are allowed in fractions so 936/1000 and when reduced/simplified, we get 117/125 hence the answer is 117.
