If PAB are secant to the circle and PT is tangent segment; then `PAxxPB=PT^2`

If PAB are secant to the circle and PT is tangent segment; then PA xx PB=PT^(2)

Let PAB be a secant to a circle intersecting the circle at A and B. Let PT be the tangent segment. If PA = 9 cm and PT =12 cm, then what is AB equal to?

In the given figure, O is the centre of the circle and PT is a tangent at T. If PC = 3 cm and PT = 6 cm, calculate the radius of the circle.

In the given figure, TB is a chord which passes through the centre of the circle . PT is a tangent to the circle at the point T on the circle . If PT=10cm , PA=5cm and AB=xcm , then the radius of the circle is :

In the figure 'O' is the centre of the circle ,PT is a tangent and if anglePTO=30^(@) , find anglePOT

In the given figure, TB is a chord which passes through the centre of the circle. PT is a tangent to the circle at the point T on the circle. If PT = 10 cm, PA = 5 cm and AB = x cm. then the radius of the circle is:

In the figure PT is a tangent to the circle with centre 'O' then x =
