find the radius of the circle

Question

OABC is a rhombus whose three vertices A, B and C lie on a circle with centre O and the are of that rhombus is 32 & sq.3 cube cm

Answer 1

Δ AOB is an equilateral triangle with area of 16 cm³.

One side is the radius.

A = (s²√3)/4

16 = (s²√3)/4

64 = s²√3

36.95 ≈ s²

6.08 ≈ s
