Step-by-step explanation:
Each triangle has the surface area of 1.5, because 1 3 = 3 / 2 = 1.5. You divide by two because it is half a rectangle instead of a full one. You multiply by four which would get you 1.5
4 = 6. The square in the middle has the surface area of 1 because 1
1 = 1. So you would get 7.
We need to convert the equation of the circle to standard form only then we can find the radius and the center of the circle.
From this equation we can write:
Center of the circle is (-1,1) and the radius of the circle is 4.
From this equation we can write:
Center of the circle is (-1,1) and the radius of the circle is 4.
