To circle with a radius of 41 cm from the point R guided two tangents. The distance of both points of contact is 16 cm. Calculate the distance from point R and circle center.

Correct answer:

d =  41.8 cm

Step-by-step explanation:

412=c1(c1+c2) 4162=c2c1  412=c12+4162 c1=4124162=40.212 cm c2=4162/c1=1.592 cm d=c1+c2=41.8 cm
