answer: 3.14
Step-by-step explanation:
The formula to find area of a circle is
radius × radius × pi since our radius is given this wont be to tough so we will just do 1 x 1 = 1 then multply that by pi so 1 × 3.14 = 3.14 so 3.14 is the area Hope that helps you!
Answer:

Answer:
No solution
Step-by-step explanation:
Substitution is done by substituting one equation into another. To begin solve one equation for a variable.
Substitute y=-4x+3 into -4x-y=-2.
-4x -(-4x + 3) = -2
-4x + 4x - 3 = -2
-3=-2
This is a false statement and there is no variable present anymore. This means the equations have no solution.
