Answer:

C = 22.56

Step-by-step explanation:

The equation for the circumference of a circle is [tex]C=2\pi r[/tex].

The radius is half the diameter so [tex]r=\frac{7.18}{2}=3.59[/tex]

Plug the radius into the equation.

[tex]C=2*\pi *3.59[/tex]

[tex]C=22.55664[/tex]

Given:

Diameter of circle = 7.18 m

To find:

Circumference of the circle

Steps:

We know that radius is equal to half of the diameter

r = d/2

r = 7.18/2

r = 3.59 m

Now circumference is equal 2πr

Circumference = 2πr

Circumference = 2 × 3.14 × 3.59      (taking pi as 3.14)

Circumference = 6.28 × 3.59

Circumference = 22.5452

Circumference ≈ 22.55 meters

Therefore, the circumference of the circle is approximately 22.55 meters
