Answer» - Two circles of equal radius 6 CM such that the distance between their centres is 15 cm, find the length of transverse common tangent ? Solution :- we know that, if two circles having radius as r1 and R2, and distance between their centres is d , then, Length of transverse common tangent = √[(d)² - (r1 + r2)²] .here, we have ,d = 15cm.r1 = r2 = 6 cm. So, → Length of transverse common tangent = √[(d)² - (r1 + r2)²] → Length = √[(15)² - (6 + 6)²] → Length = √(225 - 144) → Length = √(81) → Length = 9 cm. (Ans.) Hence, the length of transverse common tangent is 9CM.
