Please I need to get this right!!

12.56

Step-by-step explanation:

The formula for circumference is:

Circumference = Pi x Diameter

In this case the diameter is 4.

So you can simplify Pi to just 3.14 and multiply that times 4 which gives you 12.56.

Hope this helped!

:25.13

25.13

Step-by-step explanation: C=2πr=2·π·4≈25.13274

This is the correct answer to the question and thats the explanation

It wont let me turn it in for some reason

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
