Answer:

A≈50.27

Step-by-step explanation:

The formula for an Area of a circle is: A=πr(squared)

As was can the the diametter is 4, and the radius is half of the diameter, making the radius half of 4 whitch is 2. now just plug in two for R.

A= π4(squared)

4(squared) = 16

A= 16π

A= 50.27

Identify the coordinates of the image of vertex M under a dilation centered at the origin with a scale factor of 1/2

poizon [28]

Answer:

(2,0)

Step-by-step explanation:

The current coordinate of M are (4,0). This means the side length of OM is 4. To scale down by a factor of 1/2, the side length would become 4*1/2 = 2.

This side is now 2 and would place the point M at (2,0).
