So set up the equations
q-12=d
25q+10d=1105
plug in q-12 as d in the second equation:
25q+10q-120=1105, then simplify:
35q=1225
q=35
since there's 12 fewer dimes, we know that there's 23 dimes and 35 quarters.
The answer of this question is going to be B then on 2 A then D
The lateral area of cylinder is 2 pi r h all multiplied by each other
r = d/2 r = 5
h = 10
2 pi (5)(10)
the answer is 100(pi)
hope it helps :)
