Diameter for the semicircle acting also as the base of the triangle attached, total area is sum of the areas of the semicircle and triangle. This base and diameter is 2%2Ar.

A=%281%2F2%29%282r%29%2Ah%2B%281%2F2%29pi%2Ar%5E2

A=%281%2F2%29%282rh%2Bpi%2Ar%5E2%29

A=%281%2F2%29%282%2A2%2A5%2Bpi%2A2%5E2%29

A=2%2A5%2Bpi%2A2
