Question

s. Find the volume of the cylinder given the circum-
ference of the base is 176cm and height 30cm.​

Answer 1

Find the volume of the cylinder

Circumference of base => 176cm

Height => 30cm

________________________

Solution-

$circumference = > 2\pi \: r \\ \\ 176cm = > 2 \times \frac{22}{7} \times r \\ \\ \frac{176cm \times 7}{44cm} = > r \\ \\ \frac{1232}{44} = > r \\ \\ \boxed{r = > 28}$

$\color{red} \boxed{volume \: of \: cylinder = > \pi \: {r}^{2} h}$

____________________

$volume \: of \: cylinder = > \frac{22}{7} \times (28 {)}^{2} \times 30 \\ \\ = > > \frac{22}{7} \times 784 \times 30 \\ \\ = > > \frac{517440}{7} \\ \\ = > > 73920c {m}^{2}$

_____________________

The volume of cylinder is 73920cm²
