Answer:
[tex]129.5\ sec[/tex]
Step-by-step explanation:
Step 1
Find the circumference of [tex]40\%[/tex] of a circle
The formula is equal to
[tex]C=0.40(2\pi r)[/tex]
we have
[tex]r=225\ ft[/tex]
substitute
[tex]C=0.40(2\pi (225))=180 \pi\ ft[/tex]
Step 2
Find the perimeter of the baseball field
[tex]P=180 \pi+300*2=1,165.49\ ft[/tex]
Step 3
Find how long does it take you to run around the baseball field
Divide the perimeter by the rate
[tex]t=1,165.49/9=129.5\ sec[/tex]
