For the following questions answer them individually
Two circles of radii 4 cm and 9 cm respectively touch each other externally at a point and a common tangent touches them at the points P and Q respectively. Then the area of a square with one side PQ, is
Two tangents are drawn from a point P to a circle at A and B. 0 is the centre of the circle. If ∠AOP = 60°. then ∠APB is
If each interior angle is double of each exterior angle of a regular polygon with n sides, then the value of n is
If the length of the side PQ of the rhombus PQRS is 6 cm and ∠PQR = 120°, then the length of QS, in cm, is
Two sides of a triangle are of length 4 cm and 10 cm. If the length of the third side is ‘a cm, then
If $$x=(0.08)^2$$, $$y=\frac{1}{(0.08)^2}$$ and $$z=(1-0.08)^2 - 1$$, then out of the following, the true relation is
In xy Âplane, P and Q are two points having coÂordinates (2, 0) and (5, 4) respectively. Then the numerical value of the area of the circle with radius PQ, is
