Plz help some one
A banner is made of a square and a semicircle. The square has side lengths of 26 inches. One side of the square is also the diameter of the semicircle. What is the total area of the banner? Use 3.14 for π

Is the semicircle inside or outside of the square?
My guess is that it's outside
So if that's the case (which I'm pretty sure it is), find the area of the circle, take half of it, then find the area of the square and add the two together.
Area of circle = pi*r^2 = pi*26^2 = 676pi in^2, then half of it is 338pi
Area of square = s^2 = 26^2 = 676 in^2
So, 338pi in^2 + 676 in^2 = 1737.86 in^2
So the banner has a total area of 1737.86 in^2
