The formula for Surface area of cylinder is given by
Surface area =
where r is radius and h is height
So r= 5 cm and h= 12 cm
Let's plug the values in the formula
Surface area of cylinder =
= 2(3.14)(85)
= 533.8 cm²

Answer:
the answer is the first I think
Answer:
Charles = 18
Barbara = 3
Step-by-step explanation:
<em>Currently</em>
Charles: x+15
Barbara: x
<em>In twelve years</em>
Charles: x+27
Barbara: x+12
<em>Equation </em>- Charles's age in twelve years will be double Barbara's age in twelve years. Using the information about, create the equation
x+27=2(x+12)
x+27=2x+24
x=3
