Answer:
The height at time of 12.1 seconds is approximately 729.2562 feet
Step-by-step explanation:
The general form of the quadratic regression equation is y = A + Bx + Cx²
The quadratic regression formula is given as follows;
Solving using an online quadratic regression calculator, gives;
A = 2.5643259
B = 246.6374865
C = -15.41986006
Substituting gives;
y = 2.5643259 + 246.6374865·x -15.41986006·x²
When time, x = 12.1, we have;
y = 2.5643259 + 246.6374865×12.1 -15.41986006×12.1²≈ 729.2562 feet
The height at time of 12.1 seconds ≈ 729.2562 feet.

Step-by-step explanation:
First find the circumference of the top of the barrel using the rule 2times Pi times r
Then find the area of the top of the barrel using Pi times radius squared (to the power of 2)
Multiply by two (top and bottom of the barrel)
And then using the circumference you found earlier multiply it by 8 (are of the curved surface of a barrel)
You should have two results and then add them together.
Hope this helps!
