Mensuration Practice Test 1

Volume of a cylinder = 38,808 $\mathit{c}{\mathit{m}}^3$
1 ml = $1\mathit{c}{\mathit{m}}^3$
So, 38,808 ml = 38,808 $\mathit{c}{\mathit{m}}^3$
Let the height of cylinder = h
Radius = $\frac{3}{4}\mathit{h}$
$\mathit{\pi }{\mathit{r}}^2\mathit{h}$ = 38808
$\frac{22}{7}\times \frac{9{\mathit{h}}^2}{16}\times \mathit{h}$ = 28808
${\mathit{h}}^3$ = 28808 × $\frac{16}{9}\times \frac{7}{22}$
${\mathit{h}}^3$ = 21952
h = 28 cm
So, radius = $\frac{3}{4}\times 28$ = 21 cm
Diameter = 42 cm
