Answer 1

Question:-

if the radius of a cylinder is 4 cm and height is 14cm , then the volume of cylinder is _______.

Answer:-

• The volume is cylinder is 703.36 cm³.

Given :-

• Radius = 4 cm
• Height = 14 cm

To find:-

• Volume of cylinder

Solution:-

• The value of $\pi$is 3.14

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

$\implies \: volume \: = 3.14 \times {4}^{2} \times 14 \\ \\ \implies \: volume = \: 3.14 \times 16 \times 14 \\ \\ \implies \: volume \: = 703.36 {cm}^{3}$

Hence,

The volume is cylinder is 703.36 cm³.

Answer 2

Given

• Radius of cylinder (r) = 4cm
• Height of cylinder (h) = 14cm

To find

• Volume of cylinder.

Solution

By using formula

$\underline{\boxed{Volume\: of\: a\: cylinder = πr^2h}}$

→ Volume = 22/7 × 4 × 4 × 14

→ Volume = 22 × 16 × 2

→ Volume = 44 × 16

→ Volume = 704 cm³

Hence, volume of cylinder is 704 cm³.
