Answer:

$lets \: \: find \: \: \: the \: \: \: radius \\ 2\pi \: r = 132 \\ \frac{2\pi \: r}{2\pi} = \frac{132}{2\pi} \\ r = 21.01$

$lets \: \: \: find \: \: \: the \:area \: now \\ = \pi {r}^{2} \\ = \pi \times {21.01}^{2} \\ = 1,386.76$

$lets \: fin d\: \: \: the \: \: diameter \\ = d = 2r \\ = d = 2 \times 21.01 \\ = d = 42.02$

Answer:

Proof:

By the inscribed angle theorem, we know that angle BAC is equal to angle DEC. By the second corollary to the inscribed angle theorem, we know that line segment AE is perpendicular to line segment AC. Therefore, line segment AE is tangent to circle C.

Which equations have the same value of x as 2/3(6x+12)=-24? Check all that apply.1. 4x+8=24 2. 9x+18=-24 3. 4x+12=-24 4. 18x+36/

Neko [114]

Answer: Hence, Option (6) and (8) are correct as their value is also "-8".

Step-by-step explanation:

Since we have given that

$\frac{2}{3}(6x+12)=-24$

First we need to solve to get the value of 'x' :

$\frac{2}{3}(6x+12)=-24\\\\6x+12=\frac{3}{2}\times (-24)\\\\6x+12=3\times (-12)\\\\6x+12=-36\\\\6x=-36-12\\\\6x=-48\\\\x=\frac{-48}{6}\\\\x=-8$

Therefore, x=-8

Now, we will check all the options :

1) 4x+8=24

$4x+8=24\\\\4x=24-8\\\\4x=16\\\\x=\frac{16}{4}=4$

2) 9x+18=-24

$9x+18=-24\\\\9x=-24-18\\\\9x=-42\\\\x=-4.67$

3) 4x+12=-24

$4x+12=-24\\\\4x=-24-12\\\\4x=-36\\\\x=\frac{-36}{4}=-9$

4) 18x+36/2=-24

$18x+18=-24\\\\18x=-24-18\\\\18x=-42\\\\x=-2.34$

5) 4x=-36

$x=\frac{-36}{4}=-9$

6) 4x=-32

$x=\frac{-32}{4}=-8$

7) x=-9

8) x=-8

Hence, Option (6) and (8) are correct as their value is also "-8".
