الشارح للدرس: Equation of a Sphere | نجوى
Key Points. A sphere is a three-dimensional shape where every point is a distance 𝑟 (the radius of the sphere) from the center.; A sphere centered at the point (𝑎, 𝑏, 𝑐) with radius 𝑟 has the equation (in standard form) (𝑥 − 𝑎) + (𝑦 − 𝑏) + (𝑧 − 𝑐) = 𝑟. If we are given the equation of the sphere not in standard form, we can convert it to this form using ...
