14)

check the picture below... so.. is just a semi-circle and a rectangle, nothing fancy, get their area, sum them up.

15)

so... the voter turnout, is referring to, what's the percentage that voted, which year has the highest percentage... well, we simply check the percentage of the value provided from the total eligible voters, keeping in mind that, all eligible voters are the 100%

so.. for 1944

$\bf \begin{array}{ccllll}
amount&\%\\
------&----\\
86,607,000&100\\
47,976,670&x\\
\end{array}\implies \cfrac{86,607,000}{47,976,670}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 47,976,670}{86,607,000}\implies x\approx 55.39583405498$

for 1984

$\bf \begin{array}{ccllll}
amount&\%\\
-----&-----\\
167,727,000&100\\
92,659,000&x
\end{array}\implies \cfrac{167,727,000}{92,659,000}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 92,659,000}{167,727,000}\implies x\approx 55.2439380660239$
