i dont know how to find the radius

2.5 cm

Step-by-step explanation:

Since they give you the height of the button, it is the same as the diameter.  The diameter is 2 as big as the radius so, we need to divide 5 by 2 to get the radius.

Example:  The diameter is 6, find the radius

To find the radius, divide 6 by 2

6 / 2

3 is the radius

The Actual Problem:  

Step 1:  Find the radius by dividing 5 by 2

5 / 2

2.5 cm is the radius

 2.5 cm

The height of the circle can also be classified as the diameter. The radius of a circle is the length of the midpoint to the end of the circle. The radius is half the diameter, so, we can divide.

5 / 2 = 2.5cm. is the radius

Best of Luck!

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'.

y -5 = (-1/4)(x + 8)
