How do you find the circumfrence and area of a circle? Examples please or a link to a website.

Answers

Answer 1

Answer: Area or a circle
A= 3.14 (pi) multiplied by the radius to the second power
So if a circles radius is 3 cm it would be pi multiplied by 9 which equals 28.27 cm2
Circumference
C= pi multiplied by the diameter

Answer 2

Answer: To find the corcumference of the circle the formula is 2(pi)r
to find the area of the circle the formula is (pi)(r)(r)

Determine the time needed to deliver 72 papers at rate of 9 papers in 18 minutes.

Answers

Answer: The required time needed to deliver 72 papers is 2 hours 24 minutes.

Step-by-step explanation: Given that 9 papers are delivered in 18 minutes.

We are to determine the time needed to deliver 72 papers.

We will be using the UNITARY method to solve the problem.

We have

Time needed to deliver 9 papers = 18 minutes.

So, time needed to deliver 1 minute will be

$(18)/(9)=2~\textup{minutes}.$

Therefore, time needed to deliver 72 papers is given by

$2*72=144~\textup{minutes}=(120)/(60)~\textup{hours},24~\textup{minutes}=2~\textup{hours}~24~\textup{minutes}.$

Thus, the required time needed to deliver 72 papers is 2 hours 24 minutes.

So you need to find out time. What you do is divide 72 by 9 to get 8. Once you get 8, you have to multiply it by 18. Your answer is then 144 Papers

How do I substitute this?

Answers

You want to isolate one of the variables (x or y) so you can plug it into the other equation. The easiest one is isolating the 2nd equation.

3x² - 16x + 13 - y = 0 Add y on both sides

3x² - 16x + 13 = y

You can use this and plug it into the first equation

y - 12x + 15 = 3x²

(3x² - 16x + 13) - 12x + 15 = 3x²

3x² - 16x + 13 - 12x + 15 = 3x² Combine like terms

3x² - 28x + 28 = 3x² Subtract 3x² on both sides

-28x + 28 = 0 Add 28x on both sides

28 = 28x Divide 28 on both sides

1 = x

Now that you know x, you can plug it into either of the equation to find y

3(1)² - 16(1) + 13 - y = 0

3 - 16 + 13 - y = 0

-y = 0 Divide -1 on both sides

y = 0

x = 1, y = 0
