Question

Find time spent by a child during $24$ hours is shown in the pie child in each activity.

Answer 1

$\Rightarrow$ As the total angle ${360}^{\circ }=24hrs$

$\therefore 1^{\circ }=\frac{24}{{360}^{\circ }}hrs$.

$\therefore$ Time spend in sleeping $={120}^{\circ }\times \frac{24}{{360}^{\circ }}hrs=8hrs$.

Time spend in school = ${90}^{\circ }\times \frac{24}{{360}^{\circ }}=6hrs$

Time spend in playing $={45}^{\circ }\times \frac{24}{{360}^{\circ }}=3hrs$

Time spend on other activities $=3hrs$ ( $\therefore$ same angle ).

Time spend on homework $={60}^{\circ }\times \frac{24}{{360}^{\circ }}=4hrs$
