Using arc length formula find s when r=24 and θ=π/2 48π 24π 12π

bulgar [2K]

Answer:

12π

Step-by-step explanation:

The formula for arc length is given as:

$s = \frac{\theta}{360\degree} \times 2\pi r$

Plug r = 24 and θ=π/2 in the above formula, we fi d:

$s = \frac{\frac{\pi}{2}}{360\degree} \times 2\pi \times 24\\\\s = \frac{\frac{\pi}{2}}{2 \pi} \times 48\pi\\\\s = \frac{\pi}{2\times 2 \pi} \times 48\pi \\\\s = \frac{\pi}{4\pi} \times 48\pi \\\\\huge \purple {\boxed{s = 12\pi}} \\$

Answer the question below

Lena [83]

To find surface area, you would find the area of each side of the shape. Since this is a cube, each side is a square. So area=side2, So each side is 9, so 9x9=81 for each face. There are 6 faces to a cube, so 6x81=486 in2 is your answer

Identify the graph as eIdentify the graph as either y = cos x or y = sin x

serious [3.7K]

From the graph at x = 0, y = 0

Check1:
y = cosx

0 = cos(0)
0 = 1

therefore, this is not the function

Check2:
y = sinx
0 = sin(0)
0 = 0

therefore, this is the function

Conclusion:

the function in the graph is y = sinx

Answer:

see below

Step-by-step explanation:

It is easiest to compare the equations when they are written in the same form.

The first set can be written in slope-intercept form.

y = 2x +7

y = 2x +7 . . . . add 2x

These equations are identical, so have infinitely many solutions.

The second set can be written in standard form.

y +4x = -5

y +4x = -10

These equations differ only in their constant, so have no solutions.

The third set is already written in slope-intercept form. The equations have different slopes, so have exactly one solution.
