In the figure, seg MN is a chord of a circle with centre O. MN = 15, L is a point on chord MN such that ML = 9 and d( O, L ) = 5. Find the radius of the circle.

In the adjoining figure, seg MN is a chord of a circle with centre O . l(MN) = 25 . Point L on chord MN such that l(MN)=9 and l(OL)= 5, then find radius of the circle.

Seg MN is a chord of a circle with centre O. MN such that ML =9 and d(O,L)=5. Find the radius of the circle.

In the figure , seg AB is the chord of the circle with centre O. if AM =4 cm then find MB and AB. State your reason.

In the adjoining figure,seg QR is a chord of the circle with centre O. P is the midpoint of the chord QR. If QR=24, OP=10, find radius of the circle. To find solutions of the problem , write the theorems that are useful , Using them, solve the problem.

In the figure, O is the centre of a circle and diameter AB bisects the chord CD at a point E such that CE = ED = 8 cm and EB = 4 cm. The radius of the circle is . . . . .

In the figure, line l touches the circle with centre O at point P. Q is the midpoint of radius OP. RS is a chord thorugh Q such that chords RS || line l. If RS = 12 , find the radius of the circle.

In the following figure, point ‘A’ is the centre of the circle. Line MN is tangent at point M. If AN = 12 cm and MN = 6 cm, determine the radius of the circle.
