Question

find the volume of cylinder who's height is 5 cm and radius of base is 4.2 CM​

Answer 1

Step-by-step explanation:

let h be the height of a cylinder

therefore h=5 cm

and r be the radius of the base of the cylinder

therefore r= 4.2 cm

since we know that volume of a cylinder is

π r² h

22/7× 4.2×4.2×5

22/700×42×42×5

277.3 cm³ is the volume of a cylinder

Answer 2

Answer:

Height of Cylinder = 5 cm

Radius of Base = 4.2 cm

$\pink{volume \: of \: cylinder = \pi {r}^{2} h}$

$\frac{22}{7} \times {(4.2)}^{2} \times 5$

$= > \frac{22}{7} \times 4.2 \times 4.2 \times 5$

$= > \frac{22}{7} \times \frac{42}{10} \times \frac{42}{10} \times 5$

$= > 22 \times \frac{42}{10} \times \frac{6}{10} \times 5$

$= > 277.2 \: {cm}^{2}$
