For the first one divid 8cm and that will be 4cm then 4cm x 3.14 then you will get your answer
First off, the other comment is incorrect, it would be 8 x 3.14, and on the second one, if you can assume it’s a parallelogram, the area is base x height, 13 x 6 = 78. Then subtract 6 x 3.14 from it, 78 - 18.84 = 59.16
