How Do U Work Out The Area Of A Semicircle

Now, just plug "5 centimeter (2.0 in)" into the formula to get your answer. You can either use the closest approximation for π with your calculator, substitute 3.14 for π, or you can just leave the symbol in place. Here's how you do it: Area = (πr 2 )/2. Area = (π x 5 cm x 5 cm)/2. Area = (π x 25 cm 2 )/2. Formula - How to calculate the area of a semicircle from the diameter. π is approximately equal to 3.1415926535. Step 1: Find the Radius from the Diameter. Radius = Diameter ÷ 2. Step 2: Find the Area from the Radius. Area = (π x Radius 2) ÷ 2.

Math How To Calculate The Area Of A Semi circle With A Triangle Over

How Do U Work Out The Area Of A SemicircleTo find the area of the semicircle, we need to square the radius first. 6 x 6 = 36. Next we need to multiply this amount by pi (π). 36 x π = 36π. Finally we need to halve this amount. ½ x 36π = 18π = 56.5 (to 1dp) So the area of this semi-circle is 57 in 2 to the nearest square inch. The formula for the area A of a circle is built around its radius You find the area of a semicircle by plugging the given radius of the semicircle into the area of a semicircle formula The area formula is A frac pi r 2 2 A 2 r2
