Question

12. Find the volume of the cylinder. Use 3.14 for pi and round to the nearest tenth.

7 cm
2 cm
O 61.7 cm
O 110.7 cm
0 87.9 cm
O 114 cm?

Answer 1

• Volume of the cylinder is 87.9 cm³

Explanation:

Given that Radius of the cylinder is 2 cm and height is 7 cm. To find Volume of the Cylinder we will substitute the value of height and radius in given formula:

`\\ \: \: \dashrightarrow \: \: { \underline{ \boxed { \pink{ \pmb{ \mathfrak{ Volume_((Cylinder)) = \pi r^2h}}}}}} \\ \\`

Substituting the required values:

`\\ \: \: \dashrightarrow \sf \: \: Volume = 3.14 * {(2)}^(2) * 7 \\ \\`

`\: \: \dashrightarrow \sf \: \: Volume = 3.14 * 4 * 7 \\ \\`

`\: \: \dashrightarrow \sf \: \: Volume = 3.14 * 28 \\ \\`

`\: \: \dashrightarrow \: \: { \underline{ \boxed { \pink{ \pmb{ \mathfrak{ Volume = 87.9 \: {cm}^(3)}}}}}} \\ \\`

Hence,

• Volume of the cylinder is 87.9 cm³

Answer 2

Explanation:

Given :-

• Height of cylinder :- 7cm
• Base diameter of cylinder :- 2cm , radius :- 1cm

To find :-

• Volume of Cylinder

Solution :-

⇝ Volume of Cylinder = πr²h

⇝Volume = 3.14 × 1² × 6 cm³

⇝Volume = 18.84 cm³
