Find the arc length of the partial circle..

Gala2k [10]

Answer:

The arc length of the partial circle is $6\pi\ units$

Step-by-step explanation:

we know that

The circumference of a circle is equal to

$C=2\pi r$

In this problem we have a 3/4 of a circle

so

the circumference is equal to

$C=(\frac{3}{4})2\pi r$

$C=\frac{3}{2}\pi r$

we have

$r=4\ units$

substitute

$C=\frac{3}{2}\pi (4)$

$C=6\pi\ units$

Multiplying 3/7 by the reciprocal of -3/14,

$\frac{3}{7} \times \frac{14}{ - 3} \\ = \frac{1}{1} \times \frac{2}{ - 1} \\ = \frac{2}{ - 1} \\ = - 2$

Hope it helps!!

Rewrite the equation by completing the square.<br> x^2+ 12x + 36 = 0

svetoff [14.1K]

Answer:

(x+6)^2 =0

Step-by-step explanation:

x^2+ 12x + 36 = 0

Subtract 36 from each side

x^2+ 12x + 36-36 = 0-36

x^2 +12x = -36

Take the coefficient of x

12

Divide by 2

12/2 =6

Square it

6^2 =36

Add this to each side

x^2+ 12x + 36 = -36+36

(x+12/2)^2 = 0

(x+6)^2 =0
