The radius is about 50.2 m.

Step-by-step explanation: The formula to find the circumference of a circle is 2r. We know the radius is 8 and that you need to use 3.14 as pi so: 2×3.14×8 = 50.2

50.24

Step-by-step explanation:

circumference of a circle formula :D

D=diameter

radius x 2 =diameter

8 x 2 =16

16x=50.24

have a nice day!!

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
