The arc length is the measure of the distance along the curved line making up the arc<span>. It is longer than the straight line distance between its endpoints. To calculate this we simply multiply the angle to the circumference of the circle. It is expressed as:
Arc length = 2</span>πr(angle / 360)
Arc length = 2πr(50 / 360)
Arc length = 5πr / 18
Just multiply the radius then you're good. Hope this helps. Have a nice day.
Answer:
$1,221
Step-by-step explanation:
0.11×$1,100=$121
$121+ $1100= $1221

Answer:
A cylinder with height 4 units and radius 4 units
Step-by-step explanation:
Given that The coordinates A (0, 0), B (0, 4), C (4, 4), and D (4, 0) are graphed and connected together.
Since AB =BC=CD=DA we get all sides are equal
Also AB is y axis and AD is x axis, hence one angle is 90 hence all angles are 90 degrees.
Hence this is a square
When it is rotated about y axis, we gt a cylinder which has radius equal to side of the square and height also equal to the side of the square.
Answer: first option: y-axis, x-axis, y-axis, x-axis.
Justification:
The first set of reflections is like taking a ride around the block, so all the points end at the same initial point, and the final image is identical to the original image.
When you cannot figure out the result from the words in the statement, translate using math language.
Do the four reflections:
1) Reflecting a generical point, say (a,b), over the y-axis yields to keep the y coordinate and to the negative of the x-coordinate; this is, yields to coordinates (-a,b).
This is: (a,b) → (-a,b)
2) Reflecting over the x-axys yields the point (-a,b) to (-a,-b)
This is: (-a,b)→(-a,-b).
3) New reflection over the y -axis:
(-a,-b) → (-(-a), -b ) = (a, -b)
4) New reflection over the x-axis:
(a, -b) → (a, - (-b) ) = (a, b).
So, you have proved that the ending point is the same initial point. Proving tha the answer is the first set of reflections given in the list of choices.
