At a school carnival the diameter of the mat of a trampoline is 12 feet and the diameter of its metal frame is 14 feet. What is the length in feet of the metal frame that surrounds the trampoline use 3.14 r and round your answer to the nearest town.
The radius of the mat of the trampoline is half the diameter, so it is 12/2 = 6 feet. The radius of the metal frame is 14/2 = 7 feet.
The length of the metal frame that surrounds the trampoline is the circumference of the metal frame, which can be calculated using the formula: C = 2πr
C = 2 x 3.14 x 7 = 43.96 feet
Therefore, the length of the metal frame that surrounds the trampoline is approximately 44 feet.
