How do you find the area of a semicircle? - Answers

Pi X Radius SquaredDivide By 2Add Diameter/Length Of BaseThe area of a semi circle is 1/2 x pi x r2Area of circle is pi (3.14) x square of radius. Divide that by two to get half-circle.First you figure out what the area would be if it were an entire circle using the formula pi times the radius squared. Pi = approx 3.1416. Then if you know the angle (in degrees) that creates the semi circle divide that number by 360. Then multiply that number by the area of the circle.The formula for the area of a circle is A = πr2 where r is the radius and π (Pi) is the ratio of the circumference of a circle to its diameter.The area of a semicircle is thus half this quantity = πr2/2Pi r2 is the area of a circle so 1/2(Pi r2 ) is area of half circle
