\bf \textit{arc's length}\\\\ s=r\theta ~~ \begin{cases} r=radius\\ \theta =angle~in\\ \qquad radians\\ \cline{1-1} r=6\\ \theta =\frac{\pi }{3} \end{cases}\implies s=6\left( \frac{\pi }{3} \right)\implies s=2\pi \implies \stackrel{\textit{rounded up}}{s=6.3}

Answer: arc\ length=6.3\ ft

Step-by-step explanation:

You  need to use the following formula for calculate the arc lenght:

arc\ length=r\theta

Where  "r" is the radius and \theta is the central angle in radians.

You know that the central angle in radians s:

\theta=\frac{\pi }{3}

And the radius is:

r=6\ ft

Therefore, the final step is to substitute the values into the formula. Then you get:

arc\ length=(6\ ft)(\frac{\pi }{3})

arc\ length=6.3\ ft

In a cinema, there are eight seats in a row. Four of the seats in one row are occupied. What fraction of seats are available in
Anarel [89]

Answer:

<h2>\frac{1}{2}</h2>

Step-by-step explanation:

Given,

There are 8 seats in a row.

There are 8 seats in a row.4 seats are occupied.

Available seats = 8 - 4 = 4 seats

Fraction of seats available:

\frac{number \: of \: seats \: available}{total \: number \: of \: seats}

=  \frac{4}{8}

Reduce the fraction with GCF 4

=  \frac{1}{2}

Hope this helps..

Best regards!!

Roughly estimate the volume of a tennis ball in cubic cm by using 6 cm for diameter and 3 for pi. round the answer to the neares
galben [10]

The volume of ball is 113.04 cubic centimeter

<em><u>Solution:</u></em>

Given that we have to find the volume of tennis ball

Since the ball is of sphere shape, we can use the sphere formula

<em><u>The volume of sphere is given by formula:</u></em>

V = \frac{4}{3} \times \pi \times r^3

Where, "V" is the volume and "r" is the radius

Given that,

Diameter = 6 cm

Therefore,

Radius = \frac{diameter}{2}\\\\Radius = \frac{6}{2}=3

<em><u>Substituting in formula, we get</u></em>

V = \frac{4}{3} \times 3.14 \times 3^3\\\\V = 4 \times 3.14 \times 3^2\\\\V = 12.56 \times 9\\\\V = 113.04

Thus volume of ball is 113.04 cubic centimeter

X-4(3-2x) = 3(3x+4)<br> Find X
Mandarinka [93]

Answer:

all x are the solution

Step-by-step explanation:

x - 4×3 - 4×(-2x) = 3×3x + 3×4

x - 12 + 8x = 9x +12

9x + 12 = 9x + 12

9x = 9x

(0 = 0)

no matter which number we take for x the equation will always be correct

ex. x = 3 : left : 9×3 = 27

right : 9×3 = 27
