WebThis formula tells us the shortest distance between a point (𝑥₁, 𝑦₁) and a line 𝑎𝑥 + 𝑏𝑦 + 𝑐 = 0. Since the radius is perpendicular to the tangent, the shortest distance between the center and the tangent will be the radius of the circle. 𝑥 = 5 This can be rewritten as: 𝑥 - 5 = 0 Fitting this into the form: 𝑎𝑥 + 𝑏𝑦 + 𝑐 = 0 We see that: 𝑎 = 1 𝑏 = 0 WebA circle has an angle of 2 π and an Area of: πr2. A Sector has an angle of θ instead of 2 π so its Area is : θ 2π × πr2. Which can be simplified to: θ 2 × r2.
