Circles Mock Tests

If ∠AOB = 80° is the angle subtended by an arc AB at the centre O of a circle, then the angle subtended by the same arc at a point C on the remaining part of the circle is:

The circumference of a circle with radius 7 cm is:

Two circles with radii 5 cm and 3 cm touch each other externally. The distance between their centres is:

The angle subtended by a diameter at any point on the circle is:

Two tangents PA and PB are drawn to a circle with centre O from an external point P. If ∠APB = 110°, then ∠OAB is:

A tangent PQ at a point P on a circle of radius 5 cm meets a line through the centre O at Q, such that OQ = 13 cm. The length of PQ is:

A tangent at point P on a circle with centre O intersects a secant through O at point Q. If OP = 7 cm and OQ = 25 cm, then PQ is:

A tangent to a circle intersects the circle at:
