Area of the large semicircle

$= \pi{r}^{2} \div 2$

$= \frac{22}{7} \times 12 {}^{2} \times \frac{1}{2}$

$= \frac{11}{7} \times12 \times 12$

$= \frac{11}{7} \times 144$

$= 226.28$

Area of the small semicircle

$= \pi {r}^{2} \div 2$

$= \frac{22}{7} \times 6 {}^{2} \times \frac{1}{2}$

$= \frac{11}{7} \times 6 \times 6$

$= \frac{11}{7} \times 36$

$= 56.57$

Area of the figure

$= 226.28 - 56.57$

$= 169.71 {cm}^{2}$

Answer:

<h3>Negative StartFraction 7 over 10 EndFraction </h3>

Step-by-step explanation:

Given the expression $\frac{1}{2} - 1\frac{1}{5}$ , we are to find the difference

First convert the mixed fraction $1\frac{1}{5}$ to improper fraction

$1\frac{1}{5}$ = $\frac{6}{5}$

The expression becomes;

$\frac{1}{2} - \frac{6}{5}$

Find LCM

$\frac{5-6}{10}$

Evaluate the resulting expression

$\frac{5-12}{10}\\\\\frac{-7}{10}$

Hence the correct option is C i.e Negative StartFraction 7 over 10 EndFraction
