Rhombus and inscribed circle

It is given a rhombus with side a = 6 cm and the radius of the inscribed circle r = 2 cm. Calculate the length of its two diagonals.

Correct result:

u =  11.2101 cm
v =  4.2819 cm

Solution:


Our quadratic equation calculator calculates it.

(v/2)2=a22+r2 v=2 a22+r2=2 0.76392+224.2819=4.2819 cm  r2=a1 a2=5.2361 0.7639=2 r2=r



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
