Question

) Draw a circle of radius 6cm. Take a point 'P' at a distance of 10cm from
the centre of the circle. From 'P', draw two tangents to the circle.​

Answer 1

Answer:

c). 48cm² is the correct answer

Step-by-step explanation:

since ∆PQO is congruent to ∆PRO.

that implies in ∆PQO, OP= 10cm , OQ=6cm

therefore, tangent is perpendicular to radius at the point of contact.

that implies PQ=√OP² - OQ² = 8cm

therefore area of ∆PQO is ½ X PQ X OQ = 24cm

therefore area of PQOR is 2 X 24= 48cm²
