Answer:
S.A. = 1,017.36
Step-by-step explanation:
S.A. =
12 x 12 x 3.14 = 452.16
3.14 x 12 x 15 = 565.2
565.2 + 452.16 = 1,017.36
Because it is given that <6 and <14 are congruent, and <10 and <15 are congruent. <14 is congruent to <15 , an
d <10 is congruent to <11 because of the

There are two ways to do this but the way I prefer is to make one of the equations in terms of one variable and then 'plug this in' to the second equation. I will demonstrate
Look at equation 1,
this can quite easily be manipulated to show 
.
Then because there is a y in the second equation (and both equations are simultaneous) we can 'plug in' our new equation where y is in the second one
which can then be solved for x since there is only one variable 
and then with our x solution we can work out our y solution by using the equation we manipulated 
.
So the solution to these equations is x=-2 when y=6
