Answer:

  • 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
