We explain how to find the area of a semicircle and provide a quick calculator to work it out for you step by step Select if you want to use the radius or diameter default is radius For the value you can choose a whole number decimal or fraction You can type a fraction by typing the numerator then then the denominator How to Find the Area of a Semicircle Step 1 Note the radius of the circle If the diameter is given find the radius by dividing the diameter by 2 For example the diameter of the circle is 14 inches then the radius of the circle is 7 inches Step 2 Find the area of the circle using the formula and by substituting the values of r and pi
The diameter of a semicircle can be easily found if any of the following values are known Area perimeter or circumference If A is the area of the semicircle then the diameter d 8A units To find the area of a semicircle using diameter first find the radius of the semicircle by dividing the diameter by 2 Once the radius is known use the formula for the area of a semicircle which is 189 215 r 178 where r is the radius of the semicircle
