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:

Perimeter= X + Y + W. Perimeter is the sum of all sides
Answer:
1.25
Step-by-step explanation:
type in your calculator:
-1.5+2.75 OR 2.75-1.5
you should get the same answer
Yes because 84+45 is 129 and 3(28+15) is 129
