Circle x has radius r x = 6 units and circumference c x = 12 π units. circle y has circumference c y = 6 units. which equation is true? 1)ry =1/2 rx 2)ry = 2πrx 3)ry = pi/3 4)ry = 3/pi

4) rY = 3/π

The offered choices are equations for rY. Two are expressing rY in terms of rX, and two are expressions for rY based on the dimensions of circle Y.

The relationship between radius and circumference for a circle is ...

... C = 2πr

solving for r, we get

... r = C/(2π)

We are given that

... rX = CY = 6

Then the relations for rY will be one of ...

The first of these matches the 4th selection:

... 4) rY = 3/π

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
