The circumference of a coin is 7.42 cm. What is the area? using 3.14 for π

salantis [7]

By the question,
π = 3.14
circumference = 7.42 cm
or,. 2πr. =7.42
or,. 2×3.14×r. =7.42
or,. 6.28r. =7.42
or,. r. =7.42÷6.28
∆. r. =1.18 cm
Again,
Area of circumference= πr^2
=3.14 × 1.18^2
=3.14 × 1.39
=4.37 cm^2

$\bf \begin{cases}

\textit{a year, thus once}
\end{array}\to &1\\

\end{cases}
\\\\\\
$

$\bf A=5280\left[ \cfrac{\left( 1+\frac{0.06}{1} \right)^{1\cdot 4}-1}{\frac{0.06}{1}} \right]$

Joe is making $485 payments monthly, but the amount gets interest on a yearly basis, not monthly, so the amount that yields interest is 485*12

also, keep in mind, we're assuming is compound interest, as opposed to simple interest
