Question

 IN RADIUS CIRCLE OF RADIUS R CONTAINS  THE TRIANGLE OF 13,13,10 THEN WHAT IS R...?

Answer 1

We will get the answer by the help of the following formula: R=S/p, (R is radius,  is area of the triangle and p is parameter of triangle)

p=(13+13+10)/2=18

S= sq root [18(18-13)(18-14)(18-15)]= 32.86

R=32.86/18=1.8 (ans)
