A silo is a composite of a cylindrical tower with a cone for a roof. Find the volume of the silo if the

xxMikexx [17]

Answer:

5127079.21 cubic feet

Step-by-step explanation:

The silo is in the shape of a cylinder and a cone.

The volume of the silo will be the sum of the volumes of the cylinder and the cone.

Therefore, its volume is:

$V = \pi r^2h + \frac{1}{3} \pi rH$

where r = radius of cylinder and cone

h = height of cylinder

H = height of cone

The radius of the base is 120 feet, the height of the roof (cone) is 25 feet. The height of the entire silo is 130 feet. This means that the height of the cylinder is:

130 - 25 = 105 feet

Therefore, the volume of the silo is:

$V = (\pi * 120^2 * 105) + (\frac{1}{3} * 120^2 * 25)\\\\V = 4750088.09 + 376991.12\\\\V = 5127079.21 ft^3$

The volume of the silo is 5127079.21 cubic feet.

Estimate 394/24 by first rounding each number so that it has only 1 nonzero digit.

larisa [96]

Answer:

48 million

Step-by-step explanation:

Since 48,000,000 has TWO non-zero numbers, not one, it can't be the

answer.

The largest digit in the given number is the ten-millions digit, so

you want to round to the nearest ten million, rather than the nearest

million.

47,859,600 rounds to 50,000,000, to one significant digit.

Normally, we would say "round to one significant digit," but you

probably have not seen that term. Your question means the same th

Find h(x) +g(x). h(x)=x^2+6x and g(x)=-2x-3

AURORKA [14]

Answer:

$h(x) + g(x) = x^{2} + 4x - 3$

Step-by-step explanation:

h(x) + g(x) = $(x^{2} + 6x) + (-2x - 3)$

$x^{2} + 4x - 3$
