WebDec 30, 2015 · The normal area of a circle is A = πr2. Since a semicircle is just half of a circle, the area of a semicircle is shown through the formula A = πr2 2. We can solve for r to show an expression for the radius of a semicircle when given the area: A = πr2 2. 2A = πr2. 2A π = r2. r = √ 2A π. WebThen the areas of your sides are lw, wh, and lh (length, width, and height). Multiply these together, and you get l²w²h²= (lwh)²=V². So to get the volume of your figure, multiply your three areas together and take the square root. ( 4 votes) Show more comments.
