Question

Solve:

$2\times \left(\frac{{115}^0}{{360}^0}\times \frac{22}{7}\times 25\times 25\right)$

Answer 1

$2\times (\frac{{115}^o}{{360}^o}\times \frac{22}{7}\times 25\times 25)$

$\Rightarrow [\frac{115}{18}\times \frac{11}{7}\times 25]$

$\Rightarrow [\frac{1265}{126}\times 125]$

$\Rightarrow \frac{15825}{126}=1254.96$.

$\therefore 2\times \frac{{115}^o}{{360}^o}\times \frac{22}{7}\times 25\times 25=1254.96$.
