How do you work out the area of a semi circle?

The formulas to calculate the area of semicircle using radius and diameter are given as, Area of a semicircle with radius = πr2/2; Area with diameter = πd2/8, where ‘r’ is the radius, and ‘d’ is the diameter. We can substitute the known value of the area in these formulas and find the missing radius and diameter.
