(a)
To find: The length of the outfield fence.
The length of the outfield fence is 335.1 ft .
Given:
The outfield is given as follows.
Calculation:
Calculate the angle in radian.
θ=96×π180=8π15 rad
Determine the length of the outfield fence by using the arc length formula.
S=rθ=200×8π15≈335.1 ft
Hence, the length of the outfield fence is 335.1 ft .
(b)
To find: The area of the warning track.
The area of the warning track is 3267.26 ft2 .
Determine the area of the warning track by subtracting the area of the field without warning track from the area of the field.
A=A1−A2=πr12θ2−πr22θ2=(2002−1902)2×8π15=3267.26 ft2
Hence, the area of the warning track is 3267.26 ft2 .
