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.

Answer: 20%
Step-by-step explanation: The first step in finding how much the quantity decreased. We do a subtraction:
and now we must know how much percentage is 16 of 80, for this we divide:
and finally we convert this decimal value to a percentage multiplying by 100%
0.2(100%) = 20%
the quantity decreased by 20%
$2.37 (the amount he spent on groceries) + <span>35¢ (or $0.35 he could spend on candy) = $2.72
Now you subtract this number from the five dollar bill to get the change.
5 - 2.72 = $2.28
His change was $2.28.
