How to solve a semicircle
WebDec 30, 2015 · 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 If given the diameter: The diameter, like in a normal circle, is just twice the radius. 2r = d r = d 2 Webwhich lets us find the circumference C C of any circle as long as we know the diameter d d. Using the formula C = \pi d C = π d Let's find the circumference of the following circle: 10 …
