To draw two tangents to a circle with centre O and radius 3 cm from a point P, 8 cm from O, we draw a circle with centre at the midpoint of OP and radius ........ cm.
Point S lies in the exterior of a circle with centre P and radius 33cm. A tangent from S touches the circle at T and ST=56cm. Find the distance of S from P.
Choose the correct answer and give justification for each. (ii) From a point Q, the length of the tangent to a circle is 24 cm. and the distance of Q from the centre is 25 cm. The radius of the circle is 7 c m 12 c m 15 c m 24.5 c m
Point a lies in the exterior of a circle with centre P and radius 7cm. A tangent through. A touches the circle at B . If AB =24 cm . Find PA.
AP and AQ are tangent drawn from a ponit A to a circle with centre O and radius 9cm. If OA = 15 cm. then AP + AQ = …….. Cm.
P is a point in the plane of a circle with centre O and radius 4 cm. If OP = 3 cm, ..... tangent/s can be drawn to the circle from point P.
Point P lies in the exterior of a circle with cnetre O and radius 5 cm. If OP = 13 cm, then what is the length of a tangnet from P to the circle ?
Point M lies in the exterior of a circle with centre A and a tangent from M touches the circle at N. If AM=41cm and MN=40cm, find the radius of the circle.
In the figure, OACB is a quadrant of a circle with centre O and radius 3.5cm . If OD=2cm , find the area of the shaded region. (usepi=(22)/(7))
