Answer: The length of FG is 5 units, which can be expressed as 5/1. Multiplying by π, we get.
Step-by-step explanation: First, we need to find the length of GH. Since triangle GCH is a 3-4-5 right triangle, we have:
GH = 4
Now, we can use the Pythagorean theorem to find the length of FG:
FG^2 = FH^2 + GH^2
FG^2 = 9 + 16
FG^2 = 25
Taking the square root of both sides, we get:
FG = 5
Therefore, the length of FG is 5 units.
