For this case, we have that by definition, the circumference of a circle is given by:

C = \pi * d

Where:

d: Is the diameter of the circle given by 2r, that is, twice the radius.

If we have a circle with a diameter equal to 8cm, then the circumference is given by:

C = \pi * 8 \ cm

Answer:

The correct answer is option 3). 8π cm

Step-by-step explanation:

<u>Formula for circumference of circle</u>

circumference  = 2πr   where r is the radius of circle.

It is given that, Circle with center D and diameter of 8 cm labeled.

<u>To find the circumference</u>

diameter = 8cm

radius = diameter/2 = 8/2 = 4

circumference  = 2πr

circumference  = 2 * π * 4 =  8π

Therefore the circumference of given circle is

The correct answer is option 3). 8π

I don’t understand this can someone please give me and example on how to do it please?
olga55 [171]
For the first one,

you multiply 5x and -5 to get -25.

Then you move the constant to the right and change the sign to get 3x= -21 +25.

Calculate the sum of -21+25 to get 4.

Divide both sides of the equation by 3 to get x=4/3.

So then your final answer is x=4
——
3


For the second one,

Distribute 7 through the parentheses to get 14x + 14+8=120

The you add 14+8 to get 22. Your equation should be 14x+22=120

Move the constant to the right side and change its sign to get 14x=120-22

Subtract 120-22 to get 98. Now your equation should be 14x=98

Divide both sides of the equation by 14 to get x=7.

Your finial answer for the second one should be x=7.

Find the amount erica owes at the end of 6 years if $60000 is loaned to her at a rate of 4% compounded monthly
RSB [31]

Answer: $76,244.51

Step-by-step explanation:

You need to use the compound interest formula here.

First of all however, you need to convert the terms to monthly figures because the interest is compounded monthly.

4% in months = 4 / 12 = 4/12%

6 years = 6 * 12 = 72 months

Now use the compound interest formula:

= Amount * (1 + rate) ^ number of years

= 60,000 * ( 1 + 4/12%) ⁷²

= $76,244.51
