Most Important Circle Question in Class 10 Optional Math | Must Watch Before Exam!
Description:
Finding the equation of a circle with radius 4 whose centre lies on 13x + 4y = 32 and touches the line 3x + 4y + 28 = 0 — this is one of the MOST REPEATED & IMPORTANT questions in Class 10 Optional Mathematics Coordinate Geometry!
In this video we solve it step-by-step using the centre-on-line condition + tangent distance = radius concept. Perfect for SEE/Board exam preparation.Complete solution of a classic Class 10 Optional Mathematics problem:
Find the equation of the circle having radius 4 units, centre lying on the straight line 13x + 4y = 32 and touching the line 3x + 4y + 28 = 0.
We use:
• Parametric form of centre (h,k)
• Distance from centre to the tangent line = radius
• Solve the resulting quadratic equation
Ideal for students preparing for SEE / board exams. Clear handwriting, detailed explanation, no shortcuts skipped.
