Question

A cylinder of dimensions 10 height radius 7m​

Answer 1

Answer:

440m^2

Step-by-step explanation:

Curved surface area of cylinder = 2πrh

=2*22/7*7*10

= 440m^2

Hence , CSA = 440 m^2

Answer 2

$\sf\footnotesize \green{\fbox{CSA \: of \: Cylinder = 2πrh}}$

$\sf {CSA \: of \: Cylinder = 2 \times \frac{22}{ \cancel7} \times 10 \times \cancel7}$

$\sf \pink{{CSA \: of \: Cylinder = 440 {m}^{2} }}$

$\sf \footnotesize \purple{\fbox{TSA \: of \: Cylinder = 2πr(h + r)}}$

$\sf {TSA \: of \: Cylinder = 2 \times \frac{22}{ \cancel7} \times \cancel7 \left(10 + 7 \right)}$

$\sf \pink{TSA \: of \: Cylinder =308 {m}^{2} }$

$\sf \footnotesize \red{\fbox{Volume \: of \: Cylinder = 2πr²h}}$

$\sf {Volume \: of \: Cylinder = 2 \times \frac{22}{ \cancel7} \times \cancel7 \times 7 \times 10}$

$\sf \pink{Volume \: of \: Cylinder \approx3077 {m}^{3} }$
