Question

When paid flat a round parachute has a diameter of 8 meters. What is the parachute’s circumference

Answer 1

Answer:

25.12 meters

Step-by-step explanation:

The circumference of a circle is given by

$c=2\pi r$ (1)

where:

$\pi\sim 3.14$

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:

$r=\frac{d}{2}=\frac{8}{2}=4 m$

And therefore, by applying eq.(1) we can find the circumference of the circle:

$c=2\pi r=2\cdot 3.14 \cdot 4 = 25.12 m$
