Answer:
150.9 cubic inches
Step-by-step explanation:
volume of he gas = volume of a cone x 3/4
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius
h = height
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
8/2 = 4 inches
1/3 (22/7 x 4^2 x 12) = 201.142857 in^3
volume of the gas = 3/4 x 201.142857 in^3 = 150.9 in^3
the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Remark
I'm not sure I know what you mean, but I will answer trying to interpret it so it fits the description of the question.
Step One: Set up the equation. The normal way of solving this would be to use the Cos function.
Cos(theta) = Adjacent / hypotenuse = x/8 Multiply both sides by 8
8*cos(theta) = x Theta = 35
8*cos(35) = x This is about as simple a way as is possible.
6.553 = the height of the sale.
Step Three: try using the reciprocal
1 / cos(35)= hypotenuse / adjacent
1/0.8191 = 8/x cross multiply
x = 0.8191 * 8
x = 6.553
Answer:

Cosine ∅ = adjacent ÷ hypotenuse
Rounded to the nearest hundredth the answer is 0.670.
Answer:
The circumference is approximately 314 inches.
Step-by-step explanation:
3.14 x r^2
3.14 x 10^2
3.14 x 100
Circumference: 314
