The radius of a circle is 8 cm and O is its centre. If angle AOB=60^(@) and AB is a chord, then what is the length of the chord AB?

Draw a circle of radius 4 cm with centre O. Draw a diameter POQ. Through P or Q draw a tangent to the circle.

Construct a regular pentagon in a circle of radius 4 cm. the following sentences are the stepts involved in the following construction. Arrange them in sequential order from first to last. (A) With D as and AB as radius draw an arc which cuts the circle with radius point C. (B) With A as centre and AB as radius draw an arc whch cuts the circle at the point C. (C) Consutruct a circle with radius 4 cm. (D) Join AB. (E) Draw two radii overline(OA) and overline(OB) such that angle AOB =72^@ . (F) Join AE, ED, DC and CB. (G) With E as centre and AB as radius draw an arc which cuts the circle at the point D.

A chord AB is drawn in a circle with centre O and radius 5 cm. If the shortest distance between centre and chord is 4 cm, find the length of chord AB?

A ABC is inscribed in a circle with centre o and radius 5 cm and AC is a diameter of the circle. If AB = 8 cm, then BC = ......... cm.
