Answer:
[tex]\frac{\pi}{2}[/tex] or [tex]~1.5708[/tex]
Step-by-step explanation:
The formula for a semi-circle's area is [tex]\frac{\pi r^2}{2}[/tex]. So, using this information, the area of the semi-circle can be found by:
[tex]=\frac{\pi1^2}{2}[/tex]
[tex]=\frac{\pi}{2}[/tex] or [tex]~1.5708[/tex]
