=78.5cm
Step-by-step explanation:
pi=3.14
formula=3.14×r×r
3.14×5×5
78.5
1. Y= 5/4x -1.4
2.Y=-2/4x -7
Formula is Y=MX+B
To solve these equations you have to make the Y separate so add or subtract the x value depending on the charge remember what you do to one side you do to the other after you divide everything by the number in the Y value and for the x you put the y value on-top and make it a fraction
