Question

find the total surface area of solid cylinder with radius 13.3 centimetre and height 10.5 CM respectively​

Answer 1

Given :

• Radius of Cylinder is 13.3 cm.
• Height of Cylinder is 10.5 cm.

To Find :

• Total Surface Area of Cylinder.

Solution :

$\longmapsto\tt{Radius=13.3\:cm}$

$\longmapsto\tt{Height=10.5\:cm}$

Using Formula :

$\longmapsto\tt\boxed{T.S.A\:of\:Cylinder=2\pi{r(r+h)}}$

Putting Values :

$\longmapsto\tt{2\times\dfrac{22}{{\cancel{7}}}\times\dfrac{{\cancel{133}}}{10}\times{(13.3+10.5)}}$

$\longmapsto\tt{\dfrac{44\times{19}}{10}\times{(23.8)}}$

$\longmapsto\tt{\dfrac{836}{10}\times{(23.8)}}$

$\longmapsto\tt{83.6\times{23.8}}$

$\longmapsto\tt\bf{1989.68{cm}^{2}\:(Approx.)}$

So ,Total Surface Area of Cylinder is 1989.68 cm²..

• C.S.A of Cylinder = 2πrh
• T.S.A of Cylinder = 2πr(r+h)
• Volume of Cylinder = πr²h

Answer 2

Answer:

$\huge{ \underline{ \boxed{ \orange{ \star{answer}{} }{} }{} }{} }{}$

Given :-

★Radius of a cylinder = 13.3 cm

★Height of the cylinder = 10.5 cm

To Find

★TSA of the cylinder

Solution :-

$\sf{ \bold{ \underline{ radius = 13.3cm}{ } }{} }{} \\ \\ \sf{ \bold{height \: = 10.5}{} }{} \\ \\ \sf{ \bold{ \red{using \: formula \: tsa }{ \: \: = 2\pi(r + h)} }{} }{} \\ \\ \sf{ \bold{substitude \: the \: value}{ \: 2 \times \frac{22}{7 } \times } }{ \frac{133}{10} } \times (133 + 10.5) \\ \\ \frac{44 \times 19}{10} \times 23.8 \\ \\ 83.6 \times 23.8 \\ \\ \sf{ \bold{ \green{ = 1989.68 {cm}^{2} }{} }{} }{}$

So Hence the TSA of the cylinder = 1989.68 sq cm
