Hi there!

Here is the formula to find the volume of a cylinder :

V = $\pi$ × r² × h

Where :

V = volume

r = radius

h = height

Now that you have your formula, replace the information you know in the formula and solve the equation :

V = $\pi$ × 4² × 3

V = $\pi$ × 48

V = 150.796447

V ≅ 150,8 feet

There you go! I really hope this helped, if there's anything just let me know! :)

For this case we have that by definition of trigonometric relations of a rectangular triangle, that the sine of an angle is given by the opposite leg to the angle on the hypotenuse of the triangle. While the tangent of the same angle is given by the leg opposite the angle on the leg adjacent to the angle.

Then, according to the figure we have:

$sin (B) = \frac {7} {25} = 0.28\\tg (B) = \frac {7} {24} = 0.2917$

Answer:

$sin (B) = \frac {7} {25}\\tg (B) = \frac {7} {24}$

Yuri [45]

Answer:

34 feet

Step-by-step explanation:

From the question, we are told that:

If the room is 30 feet high at the center and 90 feet wide at the floor,

Entire width of the room = 90 feet = 2a

a = 90/2 = 45

Height of the room = b = 30 feet

Foci (c)² = a² - b²

c = √a² - b²

c = √45² - 30²

c = √1125

c = 33.541019662 feet

Approximately to the nearest whole number = 34 feet

Denise and Donna should each stand 34 ft from the outer wall so that they will be positioned at the foci of the ellipse
