Answer: 235.5 feet
Step-by-step explanation:
In this case, we have to calculate the circumference of the track. The circumference will be calculated as:
= 2πr
Diameter = 75 feet.
Radius = 75/2 = 37.5 feet
Circumference = 2πr = 2 × 3.14 × 37.5 = 235.5feet

Answer:
Your answer would be 36 kg m²/s²
____________________________________________________
Step-by-step explanation:
To find the canoe's kinetic energy, we would need to use the kinetic energy formula in order to get the actual kinetic energy of the moving canoe.
The equation for this problem would be:
With what we know from the questions, our mass would be 18, and our speed would be 2. We would plug those numbers in our equation. Your equation should look like this:
Now, we solve:
Once you're done solving, you should get the answer of 36.
Therefore, the canoe's kinetic energy would be 36 kg m²/s².
36 kg m²/s² should be your FINAL answer.

Answer:
x = 16, or if you didn't want the value for x,
2x + 3 = 35
Step-by-step explanation:
Three more: +3
Twice a number: 2x
Combined:
2x + 3 = 35.
Get rid of the 3 by subtracting it from both sides:
2x = 32
Get rid of the 2 by dividing it from both sides:
x = 16
