Answer:

452.16

Step-by-step explanation:

i got it right on test

The surface area of the cylinder is,

⇒ TSA = 452.16 cm²

We have to given that;

Height of cylinder = 6 cm

And, Diameter of cylinder = 12 cm

Hence, We get;

⇒ Radius of cylinder = 12 / 2 = 6 cm

We know that;

The formula for the total surface area of a given cylinder whose radius is r and height is h is,

TSA = 2πr (h + r)

Hence, We get;

TSA = 2πr (h + r)

TSA = 2 × 3.14 × 6 (6 + 6)

TSA = 37.68 × 12

TSA = 452.16 cm²

Thus, The surface area of the cylinder is,

⇒ TSA = 452.16 cm²

Step-by-step explanation:

The statements that are true about rectangles are mentioned in options  [tex](A),(B),(C),(E)[/tex] .

Rectangles a shape with four sides and having internal angles of  [tex]90^0[/tex]. Two of the sides are longer than the other two. The opposite sides of the rectangle are equal in length.

[tex](a)[/tex]  The opposite sides are  equal and parallel to each other.

[tex](b)[/tex]  The diagonals bisect each other but not at [tex]90^0[/tex].

[tex](c)[/tex]   Diagonals are equal in length.

[tex](d)[/tex]   The diagonals of rectangle are congruent.

[tex](e)[/tex]   The sum of interior angles is equal to [tex]360^0[/tex] .

[tex](f)[/tex]   Each interior angle is equal to [tex]90^0[/tex].

[tex](g)[/tex]   The angles of a rectangle are all congruent.

[tex](h)[/tex]    Opposite angles of a rectangle are congruent.

So, from the above mentioned properties we can assume that statements mentioned in options  [tex](A),(B),(C),(E)[/tex]  are true about rectangles.

Hence, we can say that the statements that are true about rectangles are mentioned in options  [tex](A),(B),(C),(E)[/tex] .

Answer:

Step-by-step explanation:

Part A

Since, BDFHJ is a regular pentagon,

Measure of interior angles of this pentagon = [tex]\frac{(n-2)\times 180}{n}[/tex]

= [tex]\frac{(5-2)\times 180}{5}[/tex]

= 108°

Since, ∠ABC ≅ ∠JBD [Vertical angles]

Therefore, m∠ABC = m∠JBD = 108°

Part B

m∠JBD + mCBD = 180° [Linear pair of angles]

108° + m∠CBD = 180°

m∠CBD = 180 - 108

m∠CBD = 72°

Similarly, m∠BDF + m∠CDB = 180°

m∠CDB + 108° = 180°

m∠CDB = 180 - 108

             = 72°

In ΔCBD,

m∠BCD + m∠CDB + m∠DBC = 180°

m∠BCD + 72° + 72° = 180°

m∠BCD = 180° - 144°

              = 36°

Answer: 5 cartons

Step-by-step explanation:

If the Chef wants to have a total of at least 50 eggs and each carton contains 12 eggs, divide 50 by 12 to find out the number of cartons needed and then round the number up:

= 50 /12

= 4.16

Round it up to the nearest 1:

= 5 cartons

This will ensure that there is at least 50 eggs because 5 * 12 = 60 eggs.

Answer:

$68000

Step-by-step explanation:

Tax free earning = first 4000

Tax on remaining amount = 25%

Total earning in other to have $20000 net of tax earning :

Net of tax = tax free earning + (25% * remaining amount)

Let remaining amount = x

20000 = 4000 + (0.25 * x)

20000 = 4000 + 0.25x

20000 - 4000 = 0.25x

16000 = 0.25x

x = 16000 / 0.25

x = 64000

Hence,

Total earning should be :

Tax free earning + roaming amount

4000 + 64000

= $68000

Answer:

∠ B ≈ 66.42°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cosB = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{2}{5}[/tex] , then

∠ B = [tex]cos^{-1}[/tex] ( [tex]\frac{2}{5}[/tex] ) ≈ 66.42° ( to the nearest hundredth )

Answer: The charge is equal to 1.602*10^(-17) C

Step-by-step explanation:

The elementary charge (the smallest charge that exists) is the charge of one proton (or the magnitude of the charge of a single electron), and it is equal to:

c = 1.602*10^(-19) C.

Where C stands for coulombs,

Then a charge of 100 elementary charges is equal to 100 times the charge of a single electron, this is:

Charge = 100*( 1.602*10^(-19) C) = 1.602*10^(-17) C
