I need to find the area of a semicircle with a radius of 2 units
MariettaO [177]

Answer:

6.2832 square units (rounded off to four decimal values)

Step-by-step explanation:

Area of a semicircle = \frac{1}{2} × π × r²

r (radius) = 2 units

For our semicircle the area = \frac{1}{2} × π × 2² = 6.28318530718  square units

Or 6.2832 square units (rounded off to four decimal values)
