Before we do anything we must convert radians to degrees using a table. pi/3 radians equals 60 degrees, meaning the central angle of this arc is 60 degrees. This also tells us that the length of the arc is 1/6 of the whole circumference. All we have to do now is calculate the circumference which is diameter x pi.

arc = 1/6 pi x 36
arc = 6pi cm

zvonat [6]

Answer:

x = -(4/3)

Step-by-step explanation:

$-3 (-4) \times1 = -16\\\\\mathrm{Divide\:both\:sides\:by\:}-3\left(-4\right)\times\:1\\\\\frac{-3\left(-4\right)x\times\:1}{-3\left(-4\right)\times\:1}=\frac{-16}{-3\left(-4\right)\times\:1}\\\\Simplify\\\\x=-\frac{4}{3}$

What is the volume of a right circular cylinder with a base diameter of 6 m and a height of 5 m?

lys-0071 [83]

If the diameter of it is 6, then its radius is half that.

$\bf \textit{volume of a right circular cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=3\\
h=5
\end{cases}\implies V=(\pi )(3^2)(5)$

Evaluate j/k -0.2k when j =25 and k = 5

denis-greek [22]

When you have an equation that has variables and you know the value of those variables, just plug it it. So plugging the vaules we get
$\frac{25}{5}-\frac{1}{5}5$
Just evaluating we get 4

Find the x-intercept of the line whose equation is 8x + 2y = 4. 04 02 1/2

bezimeni [28]

Answer:

1/2

Step-by-step explanation:

The x-intercept is a point on the graph that is located on any point of x but must have a y-value of 0. To find the x-intercept, we must set y in the given equation equal to 0.

8x + 2y = 4

8x + 2(0) = 4

8x = 4

x = 4/8

x = 1/2
