I believe it should be 1.296 miles

11*3
10*3+3
60-30+3
(sorry if these didn't help i'm a beginner and i'm in 7th grade)
The correct option is "d".
Given that L = 0.8T²
length of pendulum = 30ft
L= 0.8T²
30 = 0.8T²
T² = 30 / 0.8
T² = 37.5
T = √37.5 = 6.1 seconds
<span>So, 6.1 is the closest to the period in seconds for a pendulum that is 30 ft long.</span>
