Find the Total surface area of each of the following cylinder
​

Answer 1

Step-by-step explanation:

$let \: \: \: radius \: \: be \: \: \: r \\ height \: \: = \: \: 7 \\ \pi \: r {}^{2} = 250 \: \: (given \: \: as \: \: bottom \: \: \: area)\ \: \\ total \: \: \: surface \: \: \: area \: \: of \: \: \: cylinder = (2\pi \: r{}^{2} + \pi \: r {}^{2} h) \\ total \: \: \: surface \: \: \: area = (2 \times 250 + 250 \times 7) \\ 250(2 + 7) = 2250 \: cm {}^{2} \: \: ans.$
