A semi-circle is half of a circle. Therefore, to find the area of a semi-circle, you just have to [[Calculate the Area of a Circle|find the area of a full circle]] and then divide it by two. It will be faster than you think. | A semi-circle is half of a circle.

#Remember to state your answer in square units. Since you're finding the area of a shape, you'll have to use square units (such as cm<sup>2</sup>) in your answer to indicate that you're working with a two-dimensional object. If you're calculating volume, then you'll be working with cubic units (such as cm<sup>3</sup>). | #Remember to state your answer in square units.
