The circumference of a circle is 16π inches. Show how you can use this information to calculate the same circle’s area.

Mathematics
1 answer:
Temka [501]2 years ago

Answer:

A = 64 pi inches ^2

Step-by-step explanation:

Circumference is equal to

C =2*pi*r  where r is the radius

16 pi = 2 * pi *r

Divide each side by 2 pi

16pi/2pi = 2pir/2pi

8 = r

The radius is 8

To find the area, we use

A = pi r^2

   =pi (8)^2

  = 64 pi

Svet_ta [14]

Answer:

1p 2p 2p 2p 5p 5p 10p

Step-by-step explanation:

Available coins that are less than 11p:  1p 2p 5p 10p

11p with two coins ⇒ 1p + 10p only

11p with three coins ⇒ 1p + 5p + 5p only

11p with three coins ⇒ 2p + 2p + 2p + 5p only

Therefore, the seven coins that Luke has are:

1p 2p 2p 2p 5p 5p 10p

Answer:

y = [-½]x + [-5]

Step-by-step explanation:

Equation describing how x and y are related can be written in slope-intercept form, y = mx + b.

m = slope = ∆y/∆x

Using two pairs of values from the table, (-2, -4) and (0, -5),

Slope (m) = (-5 - (-4))/(0 - (-2)) = -1/2

m = -½

b = y-intercept = the value of y when x is 0 = -5

b = -5

✔️To write the equation, substitute m = -½ and b = -5 into y = mx + b

Thus:

y = [-½]x + [-5]

Susan is trying to decide between two jobs. One job pays $12 per hour for the first 36 hours and $15 per hour for any additional
nasty-shy [4]

Answer:

For the first question (For which job will she earn more if she works 40 hours a week), the answer is the second job.

For the second question (How much more per year will this be if she works 50 weeks per year), the answer is 25$ extra a year.

First i multiplied $12 times 36.

$12 x 36 = $432

Then i multiplied $15 times 4.

$15 x 4 = $60

Now add those together

$432 + $60 = $492

That's how much she would make in a week for the first job, if she worked 40 hours a week.

For the second job, i did the exact same process.

$11.50 x 35 = $402.5

$18 x 5 = $90

$402.5 + $90 = $492.5

She would get 50 more cents a week, if she worked 40 hours a week.

For the second question, i multiplied the first job total by 50, since she is working 50 weeks a year.

$492 x 50 = $24,600

Thats her total of a year, for the first job.

Do this with the second job.

$492.5 x 50 = $24,625

As you can see, she would get $25 more in the second job, than the first job.

I hope this helped!
