We use y=mx+c we know that c= 4 A’s this is the y intercept . Next we need to work out the gradient(m). For every two squares along we go three squares up. This means are gradient is 1.5. Finally we input are values into the equation y=1.5x+4
Answer: 
Step-by-step explanation:
The given radical expressions are:


6.28 because pi x diameter = circumference.
( diameter = half of a circle)
Step-by-step explanation:
C = 2pi r
C/2 Pi = r.
I believe this would be the solution.
