I believe the radius of the circumscribed circle is 3.125 units. Is this correct?

Extension: The radius of in the inscribed circle is 1.5 units. – Mark Mottian · 2 years, 8 months ago

R=abc/4.area ,therefore,25/2=12.5 units. – Prasad Nikam · 2 years, 8 months ago

@Prasad Nikam – Check your reasoning. – Paramjit Singh · 2 years, 8 months ago

@Prasad Nikam – First using the cosine rule and then the extended sine rule I also got 12.5 units – Josh Rowley · 2 years, 8 months ago
