Question

the curved surface area of a cylinder of length 2.5 cm and radius 3.5 CM will be. a)500cm² b)550cm² c) 450cm² d)650cm²​

Answer 1

Hello mate..

$✿*:･ﾟ \: \huge \bf{ \color{blue}{so}}{ \color{maroon}{lu}}{ \color{red}{ti}} { \color{orange}{on}} : \smallﾟ･:*✿$

GIVEN:

• Length of the cylinder = 2.5 m.
• Radius of the cylinder = 3.5 m.

TO FIND:

Curved surface area of the cylinder.

SOLUTION:

$\tt \bold \green{curved \: surface \: area \: of \: the \: cylinder = 2\pi rh}$

$\bold{⇒ 2 \times \frac{22}{7} \times 2.5 \times 3.5} \\ \bold{⇒2 \times \frac{22}{7} \times 8.75 } \\ \bold{⇒54.95}$

∴ Curved surface area of the cylinder = 550 cm².

Answer 2

Answer:

Hello mate..



GIVEN:

Length of the cylinder = 2.5 m.

Radius of the cylinder = 3.5 m.

TO FIND:

Curved surface area of the cylinder.

SOLUTION:

\tt \bold \green{curved \: surface \: area \: of \: the \: cylinder = 2\pi rh}curvedsurfaceareaofthecylinder=2πrh

\begin{lgathered}\bold{⇒ 2 \times \frac{22}{7} \times 2.5 \times 3.5} \\ \bold{⇒2 \times \frac{22}{7} \times 8.75 } \\ \bold{⇒54.95}\end{lgathered}⇒2×722×2.5×3.5⇒2×722×8.75⇒54.95

∴ Curved surface area of the cylinder = 550 cm².
