Problema Solution
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 for π and round your answer to the nearest tenth.
Answer provided by our tutors
We need to find the circumference of a circle with diameter d = 14 ft.
C = π*d
C = 3.14*14
C = 43.96 ft
The length of the metal frame that surrounds the trampoline is 43.96 ft, or 44 ft rounded to the nearest integer.
