Since it is an equilateral triangle, it will be a piece of cake.

Circumcentre is the point of intersection of the perpendicular bisectors. And because the circumcentre lies at the orthocentre in equilateral triangle, we could use the height of the triangle.

Lets put in the formula.

$Height =√3/2*10cm$

$=√3(5)cm$

Since orthocentre is halfway the length of altitude in equilateral triangle, we could say that circumradius is 5√3/2vm.
