Question

total surface area of cylinder with radius 3.5m and height 15m​

Answer 1

Answer :-

• TSA of cylinder is 407 m²

Given :-

• Radius of cylinder = 3.5 m
• Height of cylinder = 15 m

To Find :-

• Total Surface Area of cylinder.

Explanation :-

We know that the Total Surface Area of cylinder can be find with the formulae,

${{{\boxed{{\Longrightarrow{TSA \:of\:Cylinder=\bold{2\pi{r(r+h)}}}}}}$

Now, Substituting the values,

$\Longrightarrow{2\times\frac{22}{7} \times{3.5\:(3.5+15)$

$\Longrightarrow{\frac{44}{7} \times{3.5\:(18.5)$

$\Longrightarrow{\frac{44}{7} \times64.75$

${{{\lhuge{{\Longrightarrow{\frac{44\:\times\:64.75}{7}}}}$

$\Huge{{\Longrightarrow{\frac{2849}{7}}}$

$\underline{\boxed{{\bold{\Longrightarrow{407 \:m^{2}}}}}}$

Hence, the TSA of cylinder is 407 m².
