two circles of radii 5 cm and 3 cm touch each other at A and also touch each other a at line B and C. the distance BC in cms is??

a) 4144
b) 8192
c) 256
d) 102

• here is the formula to solve this type of question rootover((r1+r2)^2)-(r1-r2)^2)) i.e direct common tangent formula.. put the values and u'll get the answer i.e root(60)

• BC=root(8^2-2^2)=root(60)
• 9 years agoHelpfull: Yes(3) No(2)
• BUT bro option ille

  a. 60−−√
  b. 62−−√
  c. 68−−√
  d. 64−−√
  Sol: Option A
  d2−(r1−r2)2−−−−−−−−−−−−√
  d = distance between centers
