Work out the circumference of this circle. Give your answer in terms of pi and state its units

Sati [7]

Answer:

14π cm

Step-by-step explanation:

Circumference of a circle given the diameter is :

πd

We simply substitute the value given in the image into our formula to find our answer:

πd = π×14 = 14π

Units will be cm as circumference is a length

This is our final answer as the question states to leave it in pi form .

Hope this helped and brainliest please

What is the volume of a cube whose side length is 1.8 meters?

Natalija [7]

Answer:

5.83

Step-by-step explanation:

You find volume of a cube by its side length cubed. (a^3). so 1.8 to the power of three is 5.83

I really need this done please

ehidna [41]

Explanation:

1. Alternate angles are on opposite sides of the transversal. Interior angles are angles that are between the parallel lines. (Exterior angles are outside the parallel lines.)

Two pairs of alternate interior angles are ...

∠2 and ∠7
∠4 and ∠5

2. Corresponding angles are ones that are on matching corners of the intersections of the transversal with the parallel lines. ∠2 and ∠6 are corresponding, because they both are on the Northeast corner of their respective intersections. In general, one will be an interior angle, and the other will be an exterior angle with respect to two parallel lines.

Same-side interior angles are on different corners of the intersection, and both are interior. (Same-side exterior angles are on different corners of the intersection, and both are exterior.)

Pairs of corresponding angles and pairs of same-side angles are on the same side of the transversal.

There are four pairs of corresponding angles:

∠1 and ∠5
∠2 and ∠6
∠3 and ∠7
∠4 and ∠8

3. The two pairs of same-side interior angles are ...

∠2 and ∠5
∠4 and ∠7

If either pair has a sum of 180°, lines p and q will be parallel.

If points A and B are randomly placed on the circumference of a circle with a radius of 2 cm, what is the probability that the l

OLga [1]

Answer:

The probability that the length of chord AB > 2 cm is 2/3 ⇒ D

Step-by-step explanation:

* Lets explain how to solve the problem

- Points A and B are randomly placed on the circumference of a

circle with a radius of 2 cm

- We need to find the probability that the length of chord AB is

greater than 2 cm

- Probability = required length of arc / circumference

- Assume that the length of the chord AB is 2 and the center of

the circle is labeled M

- The radius of the circle is 2 and AB = 2

- In Δ AMB

∵ MA= MB = 2 radii

∵ AB = 2

∴ Δ AMB is an equilateral triangle

∴ m∠AMB = π/3

∵ The length of an arc = r Ф , where r is the radius of the circle and

Ф is the central angle subtended by this arc

∵ r = 2 , Ф = π/3

∴ The length of arc AB = 2 × π/3 = 2π/3

- The arc AB is in the half of the circle then there are another arc

with the same length in the other half of the circle

- The length of the arc we must excluded from the length of the

circle to have the part of length of AB is greater than 2 is

2(2π/3) = 4π/3

∴ The length of the excluded arc is 4π/3

∵ The length of the circle is 2πr

∵ r = 2

∴ The length of the circle = 2π(2) = 4π

- The required arc = length circle - length excluded arc

∵ The length of the excluded arc = 4π/3

∵ The length of the circle = 4π

∴ The required arc = 4π - 4π/3 = 8π/3

- Probability = required length of arc / circumference

∴ Probability = (8π/3)/(4π) = 2/3

∴ The probability that the length of chord AB > 2 cm is 2/3

PLZ I NEED THIS ASAP!!! ILL GIVE YOU BRAINLIST!!!!

dusya [7]

Answer:

x and y do not have a proportional relationship. The constant would be 1.7

Step-by-step explanation:

The reason for this is because as the miles increase they are not following a straight pattern. While 14+14=28 and 28+14=42, 42+14 doesn't equal 70. Even if you think about it in a sense of multiplication, while 14x2=28, 28x2 does not equal 42. What should be done is that the opposite factor of each number should be added together and divided by 3. So 28/14=2, 42/28=1.5, and 70/42=1.6. Then you should take the numbers 2, 1.5, and 1.6, add them together and divide by 3. The answer that you should recieve is 1.7.

Hope that helped.
