Question

Find the total surface area of cylinder whose radius is 7m and height is 7m

Answer 1

Answer:

total surface area = 2πr (h+r)

= 2π(7)(7+7)

= 2π(7)( 14)

= 196π

Answer 2

$\huge{ \red{\mathfrak{solution}}}$

Given:

• Radius of the cylinder= 7m

•Height of the cylinder=7m

To find :

•Total surface area of the cylinder

As we know that ,

Total Surface area of the cylinder =

$\boxed{\bold{2\pi \: r(r + h)}}$

$\implies \: 2 \times \frac{22}{7} \times 7(7 + 7) \\ \\ \rightarrow \: 2 \times \frac{22}{ \cancel{7}} \times \cancel{7}(14) \\ \\ \leadsto \: 44 \times 14 \\ \\ \implies616$

Hence , the total surface area of the cylinder is

$\huge\boxed{ \green{616 {m}^{2} }}$
