A) \[24.23\]
B) \[25.47\]
C) \[25.31\]
D) \[25.44\]
Correct Answer: D
Solution :
This is a straight forward problem in calculating the total distance. The only trick is to make sure that in the cross-over lap you use the hypotenuse. The total distance must be precisely 400 m, so we must have \[400=112+\pi \left( R+0.05 \right)+\pi \left( R+5.05 \right)+{{\left( {{112}^{2}}+{{5}^{2}} \right)}^{1/2.}}\] Solving for E given 25.44m.You need to login to perform this action.
