[tex]======================[/tex]

Based on what the question gives us, we can say that 1,570 meters of wire will be needed to encircle this land. And to reach this conclusion, it is worth remembering the formula we use to calculate the length of a circle.

•And what formula is this...

•She gives herself by;

[tex] \: \boxed{ c = 2 \times \pi \times r} [/tex]

•On what:

  • C = length of a circle
  • π = constant math
  • r = radius

Knowing this formula, let's settle the question.

•It tells us that a terrain in a circular shape has a radius of 50 meters. And if you want to surround this land with 5 turns, having said that, ask us how many meters of wire will be needed.

Note:

  • To solve this question, we first need to find the circumference length of this terrain (since it is circular), and then we are going to multiply the value found by 5 (since there are 5 turns).

Let's right down the values;

  • c = ?
  • π =314
  • r = 5pm

Applying in the formula;

C = 2 × 314 × 50

C = 628 × 50

[tex] \: \boxed{ c = 314} [/tex]

Note that we found the total number of meters of wire to go around this terrain only once, as there are 5 turns, let's multiply by 5.

[tex]314 × 5 = \: \boxed{1570m} [/tex]

[tex]−−−−−−−✠−−−−−−−[/tex]
