A circle has radius 9.5 cm. Find the length of the arc intercepted by a central angle with measure 120°

Black_prince [1.1K]

Answer:

Step-by-step explanation:

Discussion

If the radius goes through 1 rotation. The "angle" gone through is 360 degrees. So the method is to figure out circumference of the circle, multiply this by a fraction involving 120, and you are done.

Formula

Arc Length = (120/360) * 2 * pi * r Substitute values into this equation.

Givens

Central angle = 120

r = 9.5

Solution

Arc Length = (120/360) * 2 * 3.14 * 9.5

Arc Length = (0.333) * 2 * 3.14 * 9.5

Arc Length = 19.87 cm

Graph the following equations on the graphs below. ( GRAPHING PAPER NEEDED, NOT A WEBSITE )

kodGreya [7K]

First, you want to identify the slopes and y-int.

Equation 1 = y = -2x + 2

Slope = -2

y-int. = 2 or (0,2)

Equationt 2 = y = 2x + 3

Slope = 2

Y-int. = 3 or (0,3)

To graph, first plot the y-intercepts. Then do the slopes.

Slope = -2

Down 2 over 1 (to the right)

Slope = 2

Up 2 over 1 (to the right)

Then just connect the dots in a line!

Stels [109]

$\huge\bold\color{purple}{Answer:}$

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

Explanation:

To round 129.392 to the nearest tenth consider the hundredths’ value of 129.392, which is 9 and equal or more than 5. Therefore, the tenths value of 129.392 increases by 1 to 4.

129.392 rounded to the nearest tenth = 129.4
