Circumference of the semi circle = ?r units. If we know the length of the straight line (diameter, d) in the semicircle, then we could find the radius by dividing it with 2. Circumference of the semicircle if diameter is known = `(pid)/2` units... circumference The boundary line or perimeter of a circle. centre The point inside the circle which is the same distance from all points on the circumference. radius The distance from the middle of the circle to the circumference of the circle. diameter The distance across a circle through the centre (twice the radius). chord A line segment that joins two points on the circumference, but not

## How To Find The Area And Circumference Of A Semicircle

This resource aims to build on the area of a circle by looking at the area of semi circles and quarter circles. The final activity consolidates all the learning on the area of a …

- The area of a semicircle is half the area area of the circle from which it is made. Recall that the area of a circle is πR An alternative definition of a semicircle is that it is simply an arc - a curved line that is half the circumference of a circle, without the straight line linking its ends. This means it is not a closed figure, and so: Has no area ; Has no perimeter. Its length is
