Best ResponseYou've already chosen the best response.2solve for y and get y = sqrt(a^2x^2) < equation for a semi circle integrate this from a to a dw:1352793815172:dw once you integrate it you will get \[\Pi a^2 / 2 \] since you found the area of a semicircle multiply it by 2 to get the area of the circle which is \[\Pi a^2\]
