<h3>What is a circle?</h3>
A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.
The circumference of the ring if the radius is 1 meter is,
Circumference of the ring = 2πr = 2 × π × 1 = 6.2831 meters
Hence, the circumference of the ring of fire is 6.2831 meters.

Answer:
1 1/2
Step-by-step explanation:
f(X)=3/x-1,g(x)=2/x
g.f(-5)=g(f(-5))=g(-3/5-1)=g(-3-5/5)=g(-8/5)=2×(-5/8)=-5/4
