Answer:
25.12 meters
Step-by-step explanation:
The circumference of a circle is given by
[tex]c=2\pi r[/tex] (1)
where:
[tex]\pi\sim 3.14[/tex]
r is the radius of the circle
In this problem, the parachute has a diameter of 8 meters:
d = 8 m
The radius of a circle is equal to half of its diameter, so the radius of the parachute is:
[tex]r=\frac{d}{2}=\frac{8}{2}=4 m[/tex]
And therefore, by applying eq.(1) we can find the circumference of the circle:
[tex]c=2\pi r=2\cdot 3.14 \cdot 4 = 25.12 m[/tex]
