Answer:
32901 gallons
Step-by-step explanation:
First, we find the volume of the cylindrical water tank when it is full.
The volume of a cylinder is given as:
V =
where r = radius and h = height of the cylinder
The diameter of the tank is 20 feet, hence, its radius is 10 feet.
Volume, V, is therefore:
V =
This is the volume of the tank, when it is full.
When it is 70% full, the volume will be:
1 cubic foot () is 7.48 gallons.
Therefore, the volume of the 70% full tank in gallons will be:
4398.23 * 7.48 = 32901.05 gallons ≅ 32901 gallons
The tank contains 32901 gallons of water.
Answer with explanation:
We have to find that function,which has range ,(¬∞,0)∪(2,∞) out of the following four trigonometric functions.
Range of a function is defined as,those values of function,if the function is →y=f(x), that is those values of y , for which x is defined.
A:→ y =sec x
x=
x is defined for , y≥1 and y≤-1.
B: →y=cot (2 x)-1
y+1=cot (2 x)
Since cotangent function is defined for all values of y, so, x∈[-∞,∞],that is ,x∈R.
So, Cot(2 x) -1, have the same range as Cot x.
C: y=Cos (x+1)
D: y=Cosec (x)+1
Range of Cosec x is, (-∞,-1] ∪ [1,∞).
Range of Cosec (x) +1 will be , (-∞,-1+1] ∪ [1+1,∞).
= (-∞, 0] ∪ [2,∞)
None of the option is true.
