Answer:

56.52

Step-by-step explanation: the equation for finding circumference is

C= 3.14 * D so just plug in the diameter and solve

56.52= 3.14 * 18

Answer:

Length of the metal frame = 56.5 feet.

Step-by-step explanation:

It has been given in the question that diameter of the trampoline mat is 16 feet and diameter of the metal frame is 18 feet.

We have to calculate the length of the metal frame that surrounds the trampoline.

Now we know that length of the outline of a circle is called as perimeter of the circle.

Therefore we will use the formula of perimeter of a circle = 2πr

Here radius of the metal frame = 18/2 = 9 feet

Now perimeter of the metal frame = 2×3.14×9 = 56.5 feet

Therefore answer is 56.5 feet.
