What is the exact circumference of a circle that has a radius of 5 cm?
Answer:
0.796 (simplified) 10π (not simplified)
Step-by-step explanation:
The formula for the circumference of a circle is
2πr so we have to do is plug in 5 for our radius:
2π(5) equals .796 or can be left as 10π.
The exact circumference of a circle that has a radius of 5 cm will be 31.4 centimeters.
What is the circumference of a circle?The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle.
Then the circumference of the circle will be
Circumference = 2πr units
The radius of the circle is 5 centimeters.
Then the circumference of the circle will be
Circumference = 2πr
Circumference = 2π (5)
Circumference = 10π
We know that the value of π will be 3.14 approximately. Then we have
Circumference = 10 x 3.14
Circumference = 31.4 centimeters
The exact circumference of a circle that has a radius of 5 centimeters will be 31.4 centimeters.

Answer:
Volume (V) = 2522.0 mm^3
Step-by-step explanation:
The volume of cylinder is :
V = π r 2 h
We know that the height (h) is 19.
We also know the radius (r) is 13/2 = 6.5
So,
V = π 6.5^2*19
V = 2522.0 mm^3

Answer:
[tex]7\sqrt{3}[/tex]
Step-by-step explanation:
Since this is a 30-60-90 triangle, we know that the sides have the following characteristic:
The side opposite to 30 degree angle: n
The side opposite to 60 degree angle: [tex]n\sqrt{3}[/tex]
The side opposite to 90 degree angle: 2n
Since we know that 7 is opposite to 30-degree, and x is opposite to 60 degree, than we know that x = [tex]7\sqrt{3}[/tex]

write an explicit formula for an,the nth term of the sequence 72,12,2
Answer:
[tex]a_n = 432 \cdot \left(\frac{1}{6}\right)^n[/tex] OR [tex]a_n = 72 \cdot \left(\frac{1}{6}\right)^{n-1}[/tex]
Step-by-step explanation:
The first term is 72, and each term is equal to the previous term multiplied by 1/6. This yields the expression [tex]a_n = 72 \cdot \left(\frac{1}{6}\right)^{n-1}[/tex], which is equivalent to [tex]a_n = 432 \cdot \left(\frac{1}{6}\right)^n[/tex].
Answer:
[tex]n _{th} = n _{1} {r}^{n - 1} \\ n _{th} = 72 \times 12 {}^{(n - 1)} \\ n _{th} = 72 \times ( {12}^{n} .12^(-1)) \\ n _{th} = 6 × {12}^{n} [/tex]

Jessie and his family drove up to a picnic area on a mountain. In the morning, they followed a trail that led to the mountain summit, which was 2,000 feet above the picnic area. They then returned to the picnic area for lunch. After lunch, they hiked on a trail that led to the mountain overlook, which was 3,500 feet below the picnic area. On the number line below the location of the Picnic Area, P, is represented by the value 0; the Mountain Summit, S, is represented by the value 2,000; and the Mountain Overlook, O, is represented by the value, -3,500. O P S Write the absolute value of the elevation of the Mountain Summit and Mountain Overlook Below. Mountain Summit: |2,000| = Mountain Overlook: |-3,500| =
Answer:
i. 2000 ii. 3500
Step-by-step explanation:
Since the absolute value of a number x, |x| = x if x > 0 and |x| = -x if x < 0,
i. Absolute value of Mountain Summit
Since the Mountain Summit elevation, x = 2000 - 0 = 2000, its absolute value = |2000| = 2000
ii. Absolute value of Mountain Overlook
Since the Mountain Summit elevation, x = -3500 - 0 = -3500, its absolute value = |-3500| = -(-3500) = 3500

Which statements are necessary to prove the two triangles are congruent by SSS? (ASAP HELP PLS!!!)
Answer:
C
Step-by-step explanation:
To prove that two triangles are congruent using the SSS Congruence criterion, we must establish that all three sides of one triangle are equal to all the corresponding sides of the other.
Thus,
Side AD in ∆ADB is congruent to side AD in ∆ADC.
Side BD in ∆ADB is congruent to side CD in ∆ADC.
Side AB in ∆ADB is congruent to side AC in ∆ADC.
Therefore, based on the SSS congruence criterion, it is concluded that both triangles are congruent.
The statements necessary to prove that they are congruent by SSS is:

Answer:
1/2
Step-by-step explanation:
So lets go over what slope is.
The formula for slope is y/x
To find this, we can just count the change in y, and put it over x.
So lets see.
On the graph, we can count that y goes up by one, and that x goes to the right by 2.
So this means our slope is y/x, or 1/2.
This is our answer.
I hope this helps! :)

A quadrilateral has vertices (-5,1) (-2,5) (2,2) (-1,-2). Determine if it is a square by using the distance formula to calculate the length of the diagonals, and the slope formula to determine if the diagonals are perpendicular
Length of diagonals are :
[tex]D_1 = \sqrt{ (-5-(-1))^2 + (1-(-2))^2 }\\\\D_1 = 5\ units[/tex]
[tex]D_2 = \sqrt{(-2 -2 )^2 + (5-2)^2}\\\\D_2 = 5 \ units[/tex]
Now, Slope of both the diagonal is :
[tex]m_1 =\dfrac{1-(-2)}{-5-(-1)} \\\\m_1 = -\dfrac{3}{4}\\\\m_2 = \dfrac{5-2}{-2-2}\\\\m_2 = -\dfrac{3}{4}[/tex]
Now, product of slopes are :
[tex]m_1 \times m_2 = \dfrac{-3}{4} \times \dfrac{-3}{4}\\\\m_1 \times m_2 = \dfrac{9}{16}[/tex]
Since, the product of slope is not equal to -1 . It means that the slopes are not perpendicular.
Therefore, this quadrilateral is not square.

Answer:
d. 15.3%

P(pick a red) = 4/26 = 2/13 = .153 = 15.3%
3. A mysterious metal medallion has a mass of 3,088 grams. Water is poured into a graduated glass container with a 10-by-10 cm square base with a water level of 53.0 cm. The medallion is dropped into the container and the water level rises to 54.6 cm. Find the volume and the density of the medallion.
Step-by-step explanation:
Volume of displaced water = (10cm)(10cm)(1.6cm)
= 160 cm^3
density = mass/vol of displaced water
= 3088 grams/160 cm^3
= 19.3 g/cm^3
P.S. This is most likely a pure gold medallion.
