What is the circumference of the circle? Use StartFraction 22 over 7 EndFraction for Pi.

A circle.
d = StartFraction 35 over 2 EndFraction centimeters

44 cm
55 cm
100 cm
110 cm

B

Step-by-step explanation:

The circumference of a circle is denoted by: C = , where d is the diameter.

Here, the diameter is 35/2, so plug this in:

C =

C = (22/7) * (35/2) = 55

The answer is B.

:) Hope this helps.

55 cm

Step-by-step explanation:

If the diameter is 35/2, then the radius is 35/4.

Circumference of a circle = 2 * pi * r

C = 2 * (22/7) * (35/4)

C = 2 * (770/28)

C = 55 cm.

step-by-step explanation:

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'.
