Answer:

Area of a Circle Calculator [raw] Radius(r) millimeters(mm) centimeters(cm) ... formulas manually to find the area, circumference, radius and diameter of a circle, this ... the circumference is c = π(8) = 8π or 25.1 cm, rounded to the nearest tenth. ... a = π(25) = 25π. If rounding to the nearest tenth the area is 78.5 square inches.

<h3>Answer: x = 5</h3>

=====================

Work Shown:

Angle Bisector Theorem

9/(2x-1) = 15/3x

9*3x = 15(2x-1) ... cross multiply

27x = 30x-15

27-30x = 30x-15-30x ... subtract 30x from both sides

-3x = -15

-3x/(-3) = -15/(-3) .... divide both sides by -3

x = 5

Find the arc length of ABC .

Salsk061 [2.6K]

Answer:

C.

Step-by-step explanation:

Since the radius of the circle is 12 units, we can calculate the circumference.

2 * pi * r = 2 * pi * 12 = 24 * pi = 24pi.

The arc angle is 240 degrees, and the whole circle would be 360 degrees. So, we can set up an equation.

$\frac{24\pi }{360} =\frac{x}{240}$

$\frac{24\pi }{6} =\frac{x}{4}$

$\frac{4\pi }{1} =\frac{x}{4}$

1 * x = 4 * 4 * pi

x = 16pi

So, your answer is C.

Hope this helps!
