CHAPTER-3, CIRCLES 1. The length of tangents drawn from an external point to the circle are not equal are equal are not defined sometimes are equal 2. The tangents drawn at thp’extremities of the diameter of a circle are perpendicular equal none of these parallel 3. The two tangents from an external point P to a circle with centre 0 are PA and PB. ∠AB = 70°, then the ∠AOB is 100° 55° 80° 110° 4. If radii of two concentric circles are 5 cm and 3 cm respectively, then the length of the chord of the larger circle which touches the smaller circle is 10 cm 12 cm 8 cm 6 cm 5. The distance between two parallel tangents of a circle of radius 4 cm is 4 cm 8 cm 6 cm 2 cm 6. Number of tangents drawn at a point of the circle is/are two none infinite one 7. From a point P, length of the tangent to a circle of radius 8 cm is 15 cm. The distance of the point P from the centre of circle is 9 cm 17 cm 19 cm 12 cm 8. From a point P which is at a distance of 13 cm from the centre 0 of a circle of radius 5 cm, the pair of tangents PQ and PR to the circle are drawn. Then the area of the quadrilateral PQ OR is 65 cm^{2} 60 cm^{2} 32.5 cm^{2} 30 cm^{2} 9. The length of a tangent drawn from a point at a distance of 10 cm of circle is 8 cm. The radius of the circle is 5 cm 4 cm 6 cm 7 cm 10. Tangents from an external point to a circle are perpendicular not equal parallel equal Loading … Question 1 of 10
