Answer:
11 yard
Step-by-step explanation:
volume of a cylinder=πr²h ⇒ 3454=3.14×10²×h
⇒ h=3454/314=11 yard
Using the given equation, set H to 8 meters and solve for t:
8 = 3 + 20t -5t^2
Subtract 8 from each side:
3 + 20t -5t^2 -8 = 0
Simplify:
20t - 5t^2-5 =0
Factor out -5:
-5(t^2-4t+1)=0
Divide both sides by -5:
t^2 - 4t +1 = 0
Using the quadratic formula solve for t:
t = 2 +/- √3
t = 3.73 or 0.27
