Answer:

FV= $2,206.979

Step-by-step explanation:

Step 1: Find FV at the end of first 5 years at 6% rate;

FV=PV(1+r)^t

since it's quarterly-compounded, r/4=6%/4 = 1.5% and t=5*4= 20 periods

FV= 1000 * (1.015)²⁰

FV=1000* 1.346855

FV=$1,346.855

Step 2: Find FV of $1346.855 for the next 5 years at 10% rate;

FV=PV(1+r)^t

since it's quarterly-compounded, r/4=10%/4 = 2.5% and t=5*4= 20 periods

FV= 1346.855 * (1.025)²⁰

FV=1346.855* 1.638616

FV=$2,206.979

Find the surface area of the cylinder.

timofeeve [1]

$\bf \textit{surface area of a cylinder}\\\\
SA=2\pi r(h+r)~~
\begin{cases}
r=3.5\\
h=12
\end{cases}\implies SA=2\pi (3.5)(12+3.5)
\\\\\\
SA=7\pi (15.5)\implies SA=108.5\pi$
