Class 10th circle chapter example |
|
Answer» . The length of a tangent from a point A at distance 5 cm from the centre of the circle is 4 cm. Find the radius of the circle.Answer:Draw the diagram as shown below.Here, AB is the tangent that is drawn on the circle from a point A.So, the radius OB will be perpendicular to AB i.e. OB ⊥ ABWe know, OA = 5cm and AB = 4 cmNow, In △ABO,OA2\xa0=AB2+BO2\xa0(Using Pythagoras theorem)52\xa0= 42+BO2BO2\xa0= 25-16BO2\xa0= 9BO = 3So, the radius of the given circle i.e. BO is 3 cm.7. Two concentric circles are of radii 5 cm and 3 cm. Find the length of the chord of the larger circle which touches the smaller circle.Answer:Draw two concentric circles with the center O. Now, draw a chord AB in the larger circle which touches the smaller circle at a point P as shown in the figure below.From the above diagram, AB is tangent to the smaller circle to point P.∴ OP ⊥ ABUsing Pythagoras theorem in triangle OPA,OA2= AP2+OP252\xa0= AP2+32AP2\xa0= 25-9AP = 4Now, as OP ⊥ AB,Since the perpendicular from the center of the circle bisects the chord, AP will be equal to PBSo, AB = 2AP = 2×4 = 8 cmSo, the length of the chord of the larger circle is 8 cm ???

If p is the prime positive integer . Prove that √p is an irrational number |
| Answer» For any prime positive integer p, √p is an irrational number.Let us assume that √p is a rational number.Then, there exist positive co-primes a and b such that :-√p = a/bp = a²/b²b²p = a²p divide a²p divides a.a = pc ( positive integer c. )Now, b²p = a²b²p = p²c²b² = pc²p divide b²p divides bTherefore, p/a and p/bThis contradicts the fact that a and b are co-primes. | |
