The circumference of a circle is 22 cm.
What is the area of 1o of the circular region?
(Use = 2)
O 2.2 cm2
O 3.5 cm2
O 3.85 cm2
0 38.5 cm2

Answers

Answer 1

[tex] \bf \: Circumference \: of \: a \: circle = 2\pi \: r[/tex]

[tex] \implies22 = 2 \times \dfrac{22}{7} r[/tex]

[tex] \implies22 = \dfrac{44}{7} \times r[/tex]

[tex] \implies \: r = \dfrac{22 \times 7}{44} [/tex]

[tex] \implies \boxed{ r = \dfrac{7}{2} }[/tex]

Now,

[tex] \bf \: Area \: of \: circle = \pi {r}^{2} [/tex]

[tex] \rightarrow \: \frac{22}{7} \times ({ \frac{7}{2}) }^{2} [/tex]

[tex] \rightarrow \frac{22}{ \cancel7} \times \frac{ \cancel{49}}{4} [/tex]

[tex] \rightarrow \: 22 \times \frac{7}{4} [/tex]

[tex] \rightarrow \: 11 \times \frac{7}{2} [/tex]

[tex] \rightarrow \frac{77}{2} [/tex]

[tex] \rightarrow \: 38.5 \: cm {}^{2} [/tex]

Area of rectangle = 38.5 cm².

Yes they are similar

Answer:

Yes.

Step-by-step explanation:

The sum of the interior angles of triangles always add up to 180 degrees. The third angle of the top triangle would be 27. The third angle of the bottom triangle is 63.

Triangles are similar if the angles are the same. Therefore the 2 triangles are similar.

Step-by-step explanation:

Well hello there! My name is Lunako, and I'm here to help you out.

What we need to do:

Firstly, do you remember the formula for finding the volume of the sphere? Yep, it's 4π(r³/3)! I'll substitute r for 5.6 -- which is 11.2 divided by 2, but you knew that already right? -- and π for 3.14 -- I'm doing that for relative ease.

4(3.14) * (5.6³/3) {Firstly we need to need find the cube of 5.6. That would be 175.616. Let me show the work for that: 5.6 * 5.6 = 25 + 3 + 3 + 0.36 = 31.36; 31.36 * 5.6 = 150 + 5 + 1.5 + 0.3 + 18 + 0.6 + 0.18  + 0.036 = 155 + 1.8 + 18.6 + 0.216 = 156.8 + 18.816 = 175.616}

4(3.14) * (175.616/3) {Now divide 175.616 by 3 to get 58.5387 (rounded to 54 places).}

4(3.14) * 58.5387 {Now onto the left sides. 3.14 quadrupled is 12.56.}

12.56 * 58.5387 {Now for the last step: Multiplying 12.56 by 58.5387. The work for that is shown in the picture. You should get 735.246072.}

735.246072 in³ {While this is the answer, we need to round it to two decimal places, like in the answer choices. 6 is greater then 5, so round up to 735.25.}

735.25 in³ {And with that this problem is solved.}

The Answer:

The volume of the sphere is 735.25 cubic inches, which is D.

Nya wants to buy a sweater that had an original price of $50. The sweater is now discounted 15% and the sales tax rate is 6%. How much will Nya pay for the sweater? Round to the nearest cent (hundredths place). *

Answers

Answer:

$45.05

Step-by-step explanation:

Sale price of sweater is (1.00 - 0.15)($50), or 0.85($50) = $42.50.  Nya has to pay 6% sales tax on this $42.50.  Thus, the final amount due is

(1.00 + 0.06)($2.50) = $45.05

Answer:

46.42

Step-by-step explanation:

First step is to find the discount

Discount = original price * discount rate

= 55 * 20%

= 55*.20

=11

Take the discount from the original price and that is the new price

new price = original price - discount

= 55-11

=44

Now we need to find the tax

tax = new price * tax rate

= 44 * 5.5%

= 44 * .055

=2.42

The final price is the new price plus the tax

final price = new price + tax

= 44+2.42

=46.42

Therefore, Nya will pay $46.42 for the sweater if she buys it.

the answer is 9.14 so that means about nine servings of cereal

Step-by-step explanation:

you you divide 512 and 56 and you get a total of 9.14

one serving of cereal = 56

So, The number of servings of cereal contained in the box can be calculated by dividing the total of grams over one serving of cereal

∴ The number of servings = 512/56 and all the calculations done correctly would be the right answer

So, The correct answer is 9 8/56. Hope this helps!

6x - 15 - 2x = 3x + 21

4x - 15 = 3x + 21 ( subtract 3x from both sides )

x - 15 = 21 ( add 15 to both sides )
