Ncert -class 10 -maths -circles Welcome to your Ncert -class 10 -maths -circles 1. Section -A 1 markThe length of tangent from an external point on a circle is none of these always less than the radius of the circle always greater than the radius of the circle may or may not be greater than the radius of circle None 2. A circle can have …………..parallel tangents at a single time 1 3 2 4 None 3. A boy is whirling a stone tied with a string in a circular path, the centripetal force acts towards the center of the circular path. However, when the string breaks the centripetal force ceases and there is no force acting. Thus, the stone as per Newtons first law will continue in a straight line and fly off along the tangent to the circular path. What will be the angle between the radius of the circular path and tangential path followed when the thread breaks. 60º 180º 90º 45º None 4. How many parallel tangents can a circle have? 0 infinite 2 1 None 5. From a point P which is at 13 cm from the centre O 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 PQOR is 32.5 cm² 60 cm² 65 cm² 30 cm² None 6. Rahul found the design of a logo on internet. He found the measurements of sides to be AB = 12cm, BC = 8 cm and AC = 10 cm but could not measure AD. Based on the information provided calculate AD for him 5 cm 6 cm 7 cm 4 cm None 7. A tangent is drawn from a point at 17 cm of circle C (0, r) of radius 8 cm. The length of its tangent is ___cm 23 5 15 9 None 8. At one end A of a diameter AB of a circle of radius 5 cm, tangent XAY is drawn to the circle. The length of the chord CD parallel to XY and at a distance 8 cm from A is 15cm 23cm 5cm 9cm None 9. A tangent to a circle intersects it in______ point(s). 4 3 2 1 None 10. A line intersecting a circle in two points is called a ________. line arrow Secant line segment None 11. A tangent PQ at a point P of a circle of radius 5cm meets a line through the centre O at a point Q so that OQ=12cm. Length of PQ is : √119cm √8.5cm √13cm 12cm None 12. PA is a tangent to a Circle from a point P with centre O. Find the radius OA if PA =4cm and OP=5cm 3cm 1.5cm none 2cm None 13. If the length of tangent from a point A at a distance of 26cm from the centre of the circle is 10cm, then the radius of the circle is: 24cm 23cm 21cm 22cm None 14. A tangent PT from an outside point P is drawn to a circle with centre O. If PT=4cm and P lies 5cm away from the centre, the radius of the circle is : 4cm 3cm √5²+4² 4.5cm None 15. In the below figure, PA and PB are tangent to a Circle with centre O. If ∠AOB=120º, the ∠OPA is equal to 30º 40º 60º 15º None 16. The distance between two parallel tangents of a circle of radius 4 cm is 4 8 2 6 None 17. The length of tangents drawn from an external point to the circle are not equal are equal sometimes are equal are not defined None 18.
