Question

can someone give me answer of this question​

Answer 1

Answer:

Surface area of cylinder =

$2\pi r(h + r)$

Step-by-step explanation:

Radius= 1.4 cm

Length (h)= 5.2 cm

Surface area= 2*22/7*5.2(5.2+1.4)cm

Do the calculations pls

Answer 2

Answer:

$\huge\bf\red{58.08 cm²}$

step-by-step explanation:

Q 2.

Radius of cylinder = 1.4 cm

Length ( Height ) of cylinder = 5.2 cm

TSA of cylinder = 2ñr( h + r )

( ñ = 22/7 , r = radius , h = height )

Surface area of cylinder = 2ñr( h + r )

$= 2 \times \frac{22}{7} \times 1.4 (5.2 + 1.4)$

$= 2 \times \frac{22}{7} \times 1.4 \times 6.6$

$= 2 \times \frac{22}{ 7} \times \frac{14}{10} \times \frac{66}{10}$

$= 2 \times 22 \times \frac{2}{10} \times \frac{66}{10}$

$= \frac{2 \times 22 \times 2 \times 66}{100 \times 100}$

$= \frac{5805}{100}$

$\large\mathtt\pink{= 58.08 \: {cm}^{2} }$

$\large\mathtt\green{Surface \: area \: of \: Cylinder = 58.08 cm²}$

Hope it helps you!
