A silo is constructed using a cylinder with a hemisphere on top. The circumference of the hemisphere and the circumference of th
givi [52]
1. The surface that will be exposed to the rain is the lateral surface of the cylinder and the hemisphere.

2. The lateral area of the cylinder is a rectangle with height equal to the height of the cylinder and width equal to the circumference of the base of the cylinder.

3. the circumference of the base = 2\pir=2*\pi*5=10\pi
so the lateral area = 10\pi*h=10\pi*40=400\pi (ft^{2})

4. The surface area of a sphere is 4 \pi  r^{2}
so the surface of the hemisphere = \frac{1}{2} *4 \pi r^{2}=2 \pi (5)^{2}=50 \pi(ft^{2})

5. Total area exposed = 450\pi ft^{2}

Heng tried to define a reflection across line r.
Maurinko [17]

Answer:

Any point N on line r maps to itself.

Step-by-step explanation:

Reflection is one of the examples of solid transformation in which a given point, segment, or figure is flipped over a reference point or line to produce its image. The distance of the object to the reference point or line is the same as the distance of its image to the point or line. And both have the same size, but different orientation.

The option that does not fully define a reflection is; any point N on line r maps to itself, because no image of point N is produced after the operation.

In 2018, Yolanda paid $4,526 in Social Security tax. If the Social Security tax rate was 6.2% to the maximum income of $128,400
lana [24]

Answer:

$73000

Step-by-step explanation:

Given: Social security tax paid by Yolanda is $4562.

         6.2% tax to be paid on earning to the maximum income of $128400.

Lets assume Yolanda´s income be `x`.

Now, calculating the taxable income of Yolanda

∴ 62\% \times x= \$ 4526

⇒ \frac{62}{100} \times x= 4526

Cross multiplying both side

⇒ x= \frac{4526\times 100}{6.2}

∴x= $73000

∴ Yolanda´s taxable income is $73000.
