Question

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. A.) 37.7 feet B.) 44.0 feet C.) 75.4 feet D.) 87.9 feet

Answer 1

B

Explanation:

The length around a circle, or the circumference, can be found with the formula
`\pi d`, where d is the diameter. Therefore, the length of the frame is
`\pi \cdot 14\approx 44`. Hope this helps!

Answer 2

B

Explanation:

circumference can be found using formula 2 x pi x radius

radius of the entire trampoline = 7 ft

2 x 3.14 x 7 = 14 x 3.14 = 43.96

Rounded = 44.0 ft = B
