ghazi · Answer

i guess it's 484 pi inch square

ghazi · Answer

total area= 66*40 - (3*pi * (11)^2)= did you get this?

anonymous · Answer

i confused myself n then realized it was two questions in one. I am very sorry for the confusion but imma give u a medal anyways. sorry for confusion

ghazi · Answer

it's easy.....see there are 6 semi circle making it 3 circles of radius 11 (since diameter is 22) and total area of it = 66*40 now you've to subtract area of 6 semi circle which gives total area of icing = 66*40-(3*3.14*11*11) =484 pi
