I will select 3 points on the sphere to plug into this equation. Its really that simple. The points from item a lie on a line that passes through this point and is orthogonal to the plane containing p1 p2.
First of all clean your lens looks like there is probably a fingerprint on it. Finally multiply that value one more time by 4 and youll find that the area of the Earth is approximately 196961118 miles². Step 1 Draw a circle.
Second remove all clutter from your image. With an equation in standard form we can find the center and radius of the circle easilyOtherwise we will need to complete the square for the x or y variable or both to convert to standard form. Vec R R of the center of mass.
Multiply that value by π which comes out to approximately 492402795 miles². If youre finding the center of an existing circle then you dont need to draw a new circle. In this area of a sphere calculator we use four equations.
