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.

Your uncle has 36 coins in nickels and quarters. The value of his nickels is 1/15 of the value of his quarters. Find the number

Ostrovityanka [42]

Answer:i

Step-by-step explanation:

Total coin = 36

Let the no. Of quarter = x

No. Of nickel = 1/15 × x = x/15

So, x + x/15 = 36

Multiply each terms by 15

15x + x = 540

16x = 540

x = 540/16

x = 33.75

Nickel is x/15 = 33.75/15 = 2.25

PLEASE HELP WILL MARK AS BRAINLIEST!!!!! When is it a good idea to purchase discount points on a mortgage? Explain in complete s

olganol [36]

When discount points are paid, the bank collects a one-time fee at closing in exchange a lower mortgage rate to be honored for the life of the loan.

The banks consider this payment to be "prepaid mortgage interest". Meanwhile, mortgage interest is tax-deductible for eligible tax-filers so, for many mortgage borrowers, there's a tax advantage to paying discount points.

Find the distance between the points (8,1) and (2,10). Round decimals to the nearest tenth.

miss Akunina [59]

The nearest distance between the points (8,1) and (2,10) is 11 units, which is mentioned in and also calculated by using formula.

Step-by-step explanation:

The given is,

Two points are (8,1) (2,10)

Step: 1

By graphical method, refer the attachment,

First point (8,1)

The values of x=8 and y=1 noted in the graph

Second point (2,10)

The values of x=2 and y=10 noted in the graph

Now join the two points (8,1) and (2,10)

Measure the distance between two points, the distance is 11 units. Due to some error the value becomes 10.98 or 11.1 we need to convert the answer into nearest whole number.

( OR )

Step:1

By formula method,

Distance = $\sqrt{(x_{2} - x_{1} )^{2} +(y_{2} - y_{1} )^{2} }$ .....................(1)
