The first thing you should do for this case is to know the definition of the perimeter of the circle.
The perimeter of the circle is:
C = 2 * pi * r
Where,
r: radius of the circle.
Substituting we have:
C = 2 * (3.14) * (r).
Another alternative way is:
C = 2 * pi * (d / 2)
rewriting:
C = pi * d
Substituting we have:
C = (3.14) * d
Where d is the diameter of the circle.
Note: to complete the answer substitute the radius or the diameter of the circle in the given equations.
Answer:
C = (3.14) * d
C = 2 * (3.14) * (r).

The circumference of the circle.
A. r = 3 m, C = 18.84 m
B. r = 18.84 m, C = 118,315 m
C. r = 6 m, C = 37.68 m
D. r = 28.26 m, C = 177,473 m
Further explanation
Circles are two-dimensional builds which are sets of equidistant points at a point called the center point
The distance of these points to the center is called the radius of the circle. While the circle field is an area which is bounded by a circle
There are terms - terms commonly used in circles:
- 1. The center point
- 2. Radius
- 3. Arc
- 4. Circumference
- 5. Segment
- 6. Chord
- 7. Annulus
- 8. Diameter
- 9. Disc
- 10. Lens
Whereas circumference formula
C = 2. π. r
π = 3.14
r = radius
In the question is known radius as follows:
- A. r = 3 m
then
C = 2.3.14. 3
C = 18.84 m
- B. r = 18.84 m
C = 2.3.14. 18.84
C = 118,315 m
- C. r = 6 m
C = 2.3.14. 6
C = 37.68 m
- D. r = 28.26 m
C = 2.3.14. 28.26
C = 177,473 m
