The length of the cover that will wrap around the edge of the trampoline is 43.96 ft.
Step-by-step explanation:
Given that,
Area of trampoline,
Jeena wants to buy a cover to put around the edge of the trampoline. We need to find the length of the cover that will wrap around the edge of the trampoline. First of all, lets find the radius of trampoline. Let is is r. So,
To find the length of the cover that will wrap around the edge of the trampoline we will find circumference of the trampoline as :
So, the length of the cover that will wrap around the edge of the trampoline is 43.96 ft.
First we need to find the radius. Using Pythagorean theorem we can find the radius which is the distance between the center and any point along the circle:
r=((5-1)^2+(2-2)^2)^(1/2)
r=(4^2-0^2)^(1/2)
r=4 units.
Circumference=2pr so our circumference is 8p units^2
