Answer:
V = 314.2 ft^3
Step-by-step explanation:
The volume of a cylinder is given by
V = pi r^2 h r is the radius (5) and h is the height (4)
Using the pi button for pi
V = pi (5^2) (4)
V =314.1592654
Rounding to the nearest tenth
V = 314.2 ft^3
Answer:
$7,429 I think (it has to be 20 characters ignore this part)
Answer:
x = 10/√2 ≈ 7.07
Step-by-step explanation:
Comenzaremos por dividir el triángulo en dos partes y definir H, como en la figura adjunta.
Aplicando el teorema de Tales, sabemos que:

También sabemos que, dado que el tirángulo menor es la mitad que el triángulo mayor, la relación entre áreas es:

Dado que formamos dos triángulos rectángulos, podemos despejar el valor de H como:

Podemos entonces despejar x de la siguiente manera:

Answer:
500/50, 600/60, 700/70
Step-by-step explanation:
500/50 equals 10 and so do the others. This is because the fraction line means division.
Have a nice day!!!!!! :-)

Answer: 
This is the single fraction of -3*sqrt(13)+4*sqrt(3) up top all over 20.
sqrt = square root
=======================================================
Explanation:
Angle theta is between pi and 3pi/2. This places the angle in quadrant Q3 where both cosine and sine are negative
Use the pythagorean trig identity to get the following:

Angle beta is in Q1 where sine and cosine are positive.
Draw a right triangle with legs 3 and 4. The hypotenuse is 5 through the pythagorean theorem. In other words, we have a 3-4-5 right triangle.
Since
, this means 
Use these ideas:
- sin = opposite/hypotenuse
- cos = adjacent/hypotenuse
- tan = opposite/adjacent
In this case we have: opposite = 3, adjacent = 4, hypotenuse = 5.

To recap:

They lead to this
