Find the area of the semicircle. Either enter an exact answer in terms of \pi π or use 3.14, point, 14 for pi and enter your answer as a decimal.

Answer 1

The area of a full circle is:

Area = π·r²

where π = 3.14 and r is the radius. Plug in the value of r from your problem statement and use your calculator to compute the area of the circle. The area of the semi-circle is half of that. Don't forget the units.
