3 piano solos....each is 5/12 hr....
u can either add : 5/12 + 5/12 + 5/12 = 15/12 = 1 1/4 hrs
or u could multiply : 3 * 5/12 = 15/12 = 1 1/4 hs
either way....same answer
The right answer for the question that is being asked and shown above is that: "1. t = 1.5; it takes 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground." the axis of symmetry, and what does it represent is <span>1. t = 1.5; it takes 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground</span>
Since the distance around, or circumference, is 9, 622 ft. you need to use the formula for circumference to find the answer.
So...
9,622=

×diameter
9,622÷

= diameter
diameter = <span>3062.77772486 feet</span>
