We move the decimal point to the left by five figures to get 0.0000845
Answer:
x = -10
Step-by-step explanation:
6 = -x - 4
+4 +4
10 = -x
-10 = x
Circumference = πD
π*49 = 153.94 (We can leave it as it is because there are two halves to the circle on either side of the training track)
81*2 = 162 (There are two 81 meter lines)
153.94+162 = 315.94m
The length of the training track is 315.94m
Hope this helps! :)
