grain is stored in cylindrical structures called silos which is the best estimate for the volume of a silo with a diameter of 12
zalisa [80]
Volume of a cylinder = base x height
the base is the area of the circle at the bottom. 

To find the area of a circle, you use:
A = πr²
where r is the radius of the circle. 
radius is half of the diameter, so with a diameter of 12.3, (divide that by 2) the radius of the circle is 6.15 feet. 

A = π(6.15)²
A ≈ 118.82 

Since we know the height is 25 feet, we can solve for the area of the cylinder. 

Area of the cylinder = 118.82 x 25 = 2,970.57 feet cubed

What is the length of the hypotenuse of the triangle below
Hatshy [7]
One way to solve this is to use Pythagorean theorem: the square of one leg of triangle plus square of other leg of the triangle equals c the hypotenuse (longest side of triangle). You might see this as the formula a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse.
In this case, the legs are 3√2 and the hypotenuse is h.
Using the formula:
(3√2)² + (3√2)² = h²
18 + 18 = h²
h = 6

The other way to do this is with trigonometric angles.
Remember cosine is adjacent over hypotenuse.
cos(45°) = (3√2) / h
h = (3√2) / cos(45°)
h = 6

If f(x)=2x+5, then what is f(3)?
FromTheMoon [43]

Answer:

\Large \boxed{f(3)=11}

Step-by-step explanation:

f(x)=2x+5

For f(3), the input for the function f(x) is 3.

Let x (input) = 3.

f(3)=2(3)+5 \\\\ f(3)=6+5 \\\\ f(3)=11
