What is the area of a circle with a diameter of 150 cm?

5625π cm²

Step-by-step explanation:

Radius = 150 / 2 = 75 cm

Area = πr² = π(75)² = 5625π cm²

17662.5 (I used 3.14 instead of the regular pi but if you need to use pi the answer would be 17671.4587)

Step-by-step explanation:

First, you grab the diameter then divide that by 2 (that gives you the radius of the circle) Then, multiple 75² * 3.14 (or pi) to give you the answer!

Hope this helps! Good luck!

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

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'.
