If the radius of a circle equals 1.5 cm, find its circumference correct to three decimal places.

Answers

Answer:

the circumference is 9.424

Step-by-step explanation:

to find the circumference we need the diameter and to get the diameter from the radius you multiply by 2

1.5*2=3

now we multiply 3 by pi(3.14)

3*3.14=9.424

so 9.42 is your circumference

The radius of a circle is 6.1 cm. Find the circumference \textit{to the nearest tenth}to the nearest tenth.

Answers

Answer:

[tex]circumference = 2\pi \: r \\ = 2 \times 3.14 \times 6.1 \\ = 38.3 \: cm[/tex]

We have been given the radius of a circle is 6.1 cm. So, the Circumference of the circle is 38.3 cm.

How are the radius and circumference of a circle related?

Suppose that a considered circle has:

Circumference = C units

Radius = r units

Then, we get:

[tex]C = 2\pi r \: \rm units[/tex]

We have been given the radius of a circle is 6.1 cm.

The Circumference of the circle

[tex]C = 2\pi r \: \rm units[/tex]

[tex]C = 2\times 3.14 \times 6.1 \rm units\\\\C = 38.3cm[/tex]

Which regression Equation would best model the data

Y=mx + c

You need to get this equation either using Micro soft excel(You can search for the steps online) or using the formula below

m= n(£xy) - (£x)(£y) / [ n(£x²) - (£x)²]

For C

C= £y - m(£x) / n

You'd need to draw a diagram and figure out these values

You need to be careful and know that £x² is not same as (£x)²

Know this to avoid mistakes.

In circle L with m^KLM 54 and KL= 10 units, find the length of arc KM.

Round to the nearest hundredth.

Answers

Given:

In circle L, measure of angle KLM is 54 degrees and KL = 10 units.

To find:

The length of arc KM.

Solution:

The formula for arc length is:

[tex]s=2\pi r\times \dfrac{\theta}{360^\circ}[/tex]          ...(i)

Where, r is the radius of the circle and [tex]\theta [/tex] is the central angle in degrees.

The measure of KL is 10 units, it means the radius of the circle L is 10 units.

The measure of angle KLM is 54 degrees, it means the measure of central angle on arc KM is 54 degrees.

Putting [tex]\pi=3.14, r=10,\theta=54^\circ[/tex] in (i), we get

[tex]s=2(3.14)(10)\times \dfrac{54^\circ}{360^\circ}[/tex]

[tex]s=20(3.14)\times 0.15[/tex]

[tex]s=9.42[/tex]

Therefore, the length of arc KM is 9.42 units.

Dose anyone know how to solve this?

Strictly increasing functions:

Let a function f(a) for x = a, then,

f(a + h), for x = a + h,

If f(a + h) > f(a), we say this a strictly increasing function, as with increase in x, f(x) also increases.

In the given graph, there are straight lines so you can say increasing interval would have +ve slope.

For x = -5 to -4, it increases = [-5, -4]

For x = 1 to 3, it increases = [1, 3]

Answer: [-5, -4] , [1, 3]
