Question

Thanks bro

nd Total surface area of cylinder ka 2 formula hai na

⇒ 2πrh + 2πr^2 & 2π r(r+h)

yeh dono hai na ⇧⇧​

Answer 1

2πrh + 2πr²

take 2πr common

2πr( h + r)

2πr ( r +h)

so, we can't say that we have two formulae to find the Total surface area of cylinder,

it means that we have factorized the formula in shorter form, for our convenience
