Answer:
207.24 in²
Step-by-step explanation:
The "r" in the formula stands for the radius of the cylinder. That is half the diameter, so is 3 in. The "h" in the formula stands for the cylinder height, shown as 8 in. Put these values in the formula and do the arithmetic.
SA = 2πr(r +h) = 2(3.14)(3 in)(3 in + 8 in) = 6.28(33 in²)
SA = 207.24 in²
Let the price of one CD be c.
The 5 CDs cost 5c.
The cost of 5 CDs and a $12 DVD is
5c + 12
You don't use it usually because teachers usually say use 3.14 as an approximation
