Find the area of a circle with a<br> circumference of 11(pi)feet.

dlinn [17]

Answer:

30.25pi in terms of pi

94.985 In terms of 3.14

Step-by-step explanation:

Okay since the circumference is 11pi we know d = 11.

Meaning r = 5.5

We can solve this in terms of pi or 3.14, for this I will use both.

The formula for an area of a circle is pi*r^2

So,

5.5 * 5.5 = 30.25.

In terms of pi, the answer would be 30.25pi

In terms of 3.14 the answer would be 94.985

Use the quadratic formula to solve the equation <br><br> x^2-3x+2=0

Flura [38]

Answer:

x= 1, 2

Step-by-step explanation:

The quadratic formula is $x=\frac{-b+/-\sqrt{b^2-4ac} }{2a}$ . Here a=1, b=-3, and c=2.

Substitute and you'll have:

$x=\frac{-b+/-\sqrt{b^2-4ac} }{2a} =\frac{3+/-\sqrt{(-3)^2-4(1)(2)} }{2(1)}=\frac{3+/-\sqrt{9-8} }{2)}$

$\frac{3+/-\sqrt{1} }{2}=\frac{3+/-\sqrt{1} }{2}=\frac{3+/-1 }{2}= 2 , 1$

Jonah was standing at an elevation somewhere between-1 1/2

erma4kov [3.2K]

Answer:

$=-\frac{23}{12},\ -2$ and many others

Step-by-step explanation:

The limits given for Jonah's elevation with regards to sea level are

$-1\frac{1}{2}$ and $-2\frac{1}{3}$

Any number belonging to that interval could be the requested answer. We'll pick the exact center (mean value) between them:

$-1\frac{1}{2} =-\frac{3}{2}$

$-2\frac{1}{3}=-\frac{7}{3}$

Computing the mean value:

$\frac{1}{2}\left (-\frac{3}{2}-\frac{7}{3} \right)$

$=\frac{1}{2}\left (-\frac{23}{6}\right)$

$=-\frac{23}{12}$

Since $-2\frac{1}{3}=-2.33$

And $-1\frac{1}{2}=-1.5$

Other numbers like -1.6,-2,-2,3 can be examples of the required answer
