(1) circumference of a circle = 2π.R
(2) area of a circle = π.R²
Area = 452.16 m² (given), so we can calculate the radius:
452.16 = π.R²
452.16/π = R²
143.92 = R² → R =√143.92 ≈ 12 m
Having R = 12, now we can calculate the circumference :
circumference of a circle = 2π.R = 2.π.12 = 75.41 m

What do u mean by reflected on the axis? You want the equation?
Answer:
X = 8.3 (shortened)
<u>Steps for answer!</u>
1. Subtract 2.5x from both sides.
1.5=4x-11-2.5x
2. Simplify 4x-11-2.5 to 1.5x-11
1.5=1.5x-11
3. Add 11 to both sides.
1.5+11=1.5x
4. Simplify 1.5+11 to 12.5.
12.5=1.5x
5. Divide both sides by 1.5.
12.5/1.5=x
6. Simplify 12.5/1.5 to 8.3333338.333333.
8.333333=x
7. Switch sides.
x=8.333333
