Step-by-step explanation:
Hope this helpfull..but if it's not,im so sorry
------------------------------------------------------
Formula
------------------------------------------------------
Circumference = πD
------------------------------------------------------
Find Diameter
------------------------------------------------------
3600π = πD
D = 3600 ← Divide by π on both sides
------------------------------------------------------
Answer: Diameter = 3600 unit
------------------------------------------------------
f(x) = 2 + 3cos(10π(x - 3))
f(47) = 2 + 3cos(10(3.14)(47 - 3))
f(47) = 2 + 3cos(31.4(45))
f(47) = 2 + 3cos(1413)
f(47) = 2 + 3(0.891006524)
f(47) = 2 + 2.673019573
f(47) = 4.673019573
1 kilometer= 1000 meters
3x1000= 3000 meters
3000/ 25= 120 pool lengths
