the diagram abcdef represents a metal drinking trough made from a closed cyclindrical drum that was bisected length-wise .
the trough has a diameter of 56 cm and a capacity of 110 litres.
(i) calculate
a.) the area of the cross-section ade, [2]
b.) ab.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
