Question

Help me with this for brainiest

Answer 1

Answer:

11) 2 x 3.14 x (19/2)   > (we want to use the radius)

   2 x 3.14 x 9.5 = 59.66

12) 2 x 3.14 x (11/2)    > (we want to use the radius)

     2 x 3.14 x 5.5 = 34.54

     34.54/2 + 11 = 28.27   >(becuase it is only a semicircle)

   the plus 11 is the diameter, because the cirlce is cut in half
