Answer:
73.66 cm
Explanation:
The area of a round trampoline is 432 cm².
We need to find the length of the cover that came with Carmen’s trampoline.
The formula for the area of a circle is given by :
A = πr²
Where
r is radius of round trampoline

To find the length of the cover, we find the perimeter of Carmen’s trampoline.
Perimeter = Circumference

So, the correct option is (a) "73.66 cm".
