The volume of a sphere is given by the equation 
, where V is the volume and r is the radius.
To answer this question, simply plug the correct values into the equation:
The volume of the air in the balloon is about 113.0976 in3.
Hope this helps!!
Hello,
1)
sin x=3/5==>x=126.869897...° (since in quadrant II)
2)==>cos x<0
cos x=-√(1-sin ² x)=-√(1-9/25)=-4/5
tan x=(3/5)/(-4/5)=-3/4
cotg x=-4/3 =1/tan x
sec x=1/cos x=-5/4
cosec x=1/sin x=5/3
Answer:
10 + 8 + 10 + 10 + 10 + 10 + 8 + 8 + 6 + 6
Answer: 14 feet. a. The Pythagorean theorem is a^2 + b^2 = c^2, where a and b are the sides of a right angle. By plugging in the sides of the wall, and solving for c, you can find the answer. 10^2 + 10^2 = c^2
| 100 + 100 = c^2 | 200 = c^2 | c = sqrt 200 | c = 14. The other way to solve this would be using the trig functions. You know that the angle between the hypotenuse and the wall side is 45 degrees, so you can use Sine to determine the hypotenuse. Sine is equal to opposite over hypotenuse. Sin (45) = 10/h | Sin (45) * h = 10 | h = 10/Sin (45) | h = 14. Both of the methods result in 14.
If you start with the tens it will mess up the problem
