Best ResponseYou've already chosen the best response.1I'm not sure but.. would the radius of it be 1.5 because half of 3 is 1.5 ?

Best ResponseYou've already chosen the best response.1I got 7.065 is that right ? I did : A = pi r^2 A = 3.14 x 2.25 A = 7.065

Best ResponseYou've already chosen the best response.1now cut that in half because we only have half of the circle

Best ResponseYou've already chosen the best response.1area of rectangle = 24 area of semicircle = 3.5325 add them up to get the area of the entire figure

Best ResponseYou've already chosen the best response.1yeah you have the correct semicircle area. Now add up the two areas to get your answer
