Write area f a circle as a function of circumfrence

Mathematics
1 answer:
Y_Kistochka [10]3 years ago
4 0

circumference = 2\pi  \times r
area = \pi {r}^{2}
we want area =circumference*something
dividing our first equation by 2*pi
\frac{circumference}{2\pi}  = r
substituting in the second equation
area = \pi { (\frac{circumference}{2\pi}) }^{2}
simplifying
area = \pi(\frac{ {circumference}^{2} }{4 {\pi}^{2} } )
area =  \frac{{circumference} ^{2} }{4\pi}

How many 1/8 teaspoons are equal to 4 3/4 teaspoons?
Vinvika [58]

1. Convert fraction into same decimal.

To find this answer, we want to first convert the fraction so that the denominators are the same:

3/4 = ?/8

Divide the original denominator by the needed-to-be denominator.

8 / 4 = 2

Do reversal calculations

4 x 2 = 8

So, now that we know to multiply the original denominator by 2 to get the new denominator, multiple the numeriator by the same.

3           6

_  x 2 = _

4           8

So now, the new equation is:

How many 1/8 teaspoons are equal to 4 6/8 teaspoons.

(The reason why you must convert is because then you can simply say that the fraction is 6 1/8's, which means you just have to worry about the whole numbers.

2. Convert the whole numbers into a fraction to make it easier.

In order to convert whole numbers into fractions, first find the denominator your using. Which in this case, it is 8.

?/8

Now remember, for it to be a whole number, the numeriator and denominator MUST be the same.

8/8 = 1

Now remember, there are four 1's. Multiply the numeriator by 4, but keep the denominator the same or else the equation is ruined.

32/8 = 4

3. Add all your information together.

DO NOT forget to add the information you collected during the equation, or else you will get a wrong answer. Add the equation's final answer to the whole numbers final answer.

32 / 8 + 6 / 8 = ?

32 / 8 + 6 / 8 = 38 / 8

Well now, remember something. It is asking us, how many 1/8's were in the equation 4 3/4. We have transformed 4 3/4 into a whole equation, 38/8.

Now, all you need to do is look at the numeriator.

What number do you see?

You see 38.

The denominator is the correct denominator that you need. So, the number of the numeriator is the answer to the equation.

So, how many 1/8 are in 38/8?

38!

Solve for g gg. Give an exact answer. 10 ( 0.4 + 0.5 g ) = 4 g 10(0.4+0.5g)=4g10, left parenthesis, 0, point, 4, plus, 0, point,
kirill115 [55]

Answer:

the value of g is -4

Step-by-step explanation:

10 ( 0.4 + 0.5 g ) = 4 g

Our aim is to solve for g

multiply 10 inside the parenthesis

4+5g = 4g

Now combine like terms

Subtract 5g from both sides

4+5g-5g= 4g-5g

4=-g

Divide both sides by -1

g=-4
