A cylindrical grain bin has a radius of 7 feet and a height of 25 feet. How many cubic feet of grain can the bin hold
dimaraw [331]

Answer:

1225π

Step-by-step explanation:

The question concerns the volume of the cylinder.

The formula of the volume is:

V=\pi r^{2} h, where r is the radius and h is the height.

Plugging the given numbers into the formula, we find that:

V=\pi * 49 * 25=1225\pi

The result - 1225π shows that the cylinder can be filled fully with that given amount.

What’s the equation for X?
svetoff [14.1K]

Answer:

perimeter of rectangles = 2 ( l + b)

34 = 2 ( x + 2 + 3x - 4 )

34 = 2 ( 4x - 2 )

34 = 8x - 4

38 = 8 x

38/ 8 = x

thus , x = 4.75 inches

Together, the areas of the rectangles sum to 30 square centimeters.
Juli2301 [7.4K]

Answer:

3x+2y

Step-by-step explanation:

Find the rectangles attached

Area of a rectangle = Length * Width

A = A1+A2

given

A = 30cm²

A1 = 3 * x

A1 = 3x

A2 = 2*y

A2 = 2y

Substitute

30 = 3x+2y

Hence the required equation is 3x+2y = 30
