Answer:
25.12 meters
Step-by-step explanation:
The circumference of a circle is given by
(1)
where:
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:
And therefore, by applying eq.(1) we can find the circumference of the circle:
