\phi=\dfrac{2\pi}{3}\\
r=8 \text{ cm}\\
l=r\cdot\phi\\\\
l=8\cdot\dfrac{2\pi}{3}\\
l=\dfrac{16\pi}{3}\text{ cm}

Answer:

Arc length = Arc length = \frac{16\ pi}{3} = 16 .74 cm

Step-by-step explanation:

Given  :  when Θ = 2 pi over 3 and the radius is 8 cm.

To find  : What is the arc length .

Solution : WE have given that Θ = \frac{2\ pi}{3}

Radius = 8 cm .

Arc length =radius *  angle

Arc length = 8 *  \frac{2\ pi}{3}.

Arc length =  \frac{16\ pi}{3}.

Therefore, Arc length = \frac{16\ pi}{3} = 16 .74 cm

Which pair of undefined terms is used to define a ray?
Zigmanuir [339]

Answer:

A point and a line.

Further explanation:

Ray is part of the line with one endpoint. Ray is an endless straight path in one direction from a starting point, e.g., .

The arrow above the point shows the direction of the longitudinal beam. The length of the ray cannot be calculated.

Undefined terms are basic figure that is not defined in terms of other figures. The undefined terms (or primitive terms) in geometry are a point, line, and plane.

These key terms cannot be mathematically defined using other known words.

A point represents a location and has no dimension (size).  It is labeled with a capital letter and a dot.

A line is an infinite number of points extending in opposite directions that have only one dimension. It has one dimension. It is a straight path and no thickness.

A plane is a flat surface that contains many points and lines.  A plane extends infinitely in all four directions.  It is two-dimensional.  Three noncollinear points determine a plane, as there is exactly one plane that can go through these points.

Suppose a triangle has sides a, b, and c and the angle opposite the side of length a is acute what must be true?
ANTONII [103]

The true statement about the triangle is (a) b^2 + c^2 > a^2

<h3>How to determine the true inequality?</h3>

The sides are given as:

a, b and c

The angle opposite of side length a is an acute angle

The above means that:

The side a is the longest side of the triangle.

The Pythagoras theorem states that:

a^2 = b^2 + c^2

Since the triangle is not a right triangle, and the angle opposite a is acute.

Then it means that the square of a is less than the sum of squares of other sides.

This gives

a^2 < b^2 + c^2

Rewrite as:

b^2 + c^2 > a^2

Hence, the true statement about the triangle is (a) b^2 + c^2 > a^2
