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

Which relationship between x and y in the equation shows a proportional relationship
balandron [24]

Answer:

The equation y = 3x shows a proportional relationship between x and y

Step-by-step explanation:

  • <em>The proportional relationship is represented graphically by a line passes through the </em><em>origin point </em>
  • <em>The equation of the proportional relationship is </em><em>y = m x</em>

Let us solve the question

Substitute x by 0 to find the value of y, if y = 0, then the line represents this equation passes through the origin point, then the equation shows a proportional relationship

∵ y = 3x

∵ x = 0

∴ y = 3(0)

∴ y = 0

→ That means the line that represents the equation passes through

   the origin point

∴ The equation y = 3x shows a proportional relationship between x and y

What is the value of y in the equation 9 + y = 8? this is extremely time sensitive
adoni [48]

You have to switch the 8 to the left and the y to the right which would change the equation to 9-8=y

y=1
