Find the area of a regular hexagon with radius 12 in round to the nearest whole number

There are four formulas for polygon area.

area = circumradius^2 * n*sin (360/n) / 2

where "n" is the number of sides and we'll assume the radius is the circumradius

area = 12^2 * 6*sin (360/6) / 2

area = 144 * 6 * 0.86603 / 2

area = 374.12496
