The distance x that it swims is directly proportional to the time t that it swims at a constant speed v:
X=vt
V= 69miles/hour
X=69t, with t in hours, x in miles
The diameter is 5.72958
(in order to find the diameter use the equation d= C/pi )
Answer:
36.
Step-by-step explanation:
sec^2 (π/9) = 1 / cos^2 (π/9) = 1.13247
sec^2 (2π/9) = 1 / cos^2 (2π/9) = 1.70409
sec^2 (4π/9) = 1 / cos^2 (4π/9) = 33.1634
Adding these gives us 36 to the nearest whole number
