Let's begin by listing out the information given to us:

We are to find the value of y
To do this, use this formula=The area is always pie times the radius to the 2nd. But this is for a semicircle so divdie your answer by 2
The coefficient C-term is 1 in problem. The coefficient is the number before the variable of said equation. Example, the coefficient of X for thus problem 4x-4y is 4 the number BEFORE the variable, never variable itself it won’t ever be 4x
