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: C. LA
Explanation:
Angle W = Angle R (given)
VU = ST (given)
Angle U = Angle T = 90 (right angle of the right triangle)
Then we can say that triangle VWU = SRT (ASA)
