At a school carnival, the diameter of the mat of a trampoline is 16 feet and the diameter of its metal frame is 18 feet. what is the length, in feet, of the metal frame that surrounds the trampoline? use 3.14 for π and round your answer to the nearest tenth.

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.

step-by-step explanation:

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
