TS EAMCET · Maths · Properties of Triangles
In , if , then the ratio of the circumradius to its inradius is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
We know R=abc4∆, r=∆s. So Rr=abc4∆∆s=abc×s4∆2 Now a=4k, b=5k, c=6k s=a+b+c2=15k2 ⇒Rr=4k×5k×6k×15k4×2×ss-as-bs-c ⇒Rr=225k415k2×7k2×5k2×3k2=167
