Answer 1

the answer is 11 as DS is equal to 5 and by the property tangents from same point to the circle are equal we have RD equal to 5 so a r is equal to 18 now again by the same property we haveECU equal to 18 and subtracting it from abc have BQ equal to 11 now we can improve the inner quadrilateral as a rectangle by the property tangent to a radius is perpendicular through point of contact and hence we get angle A and angle as to be 90 degree The Other Angle B is given 90° so that the left angle is also 90 degree now the quadrilateral is a rectangle and the rectangle has opposite sides to be equal so the radius of the circle comes out to be 11 cm or the unit
