Question

the volume of a cylinder is 47432 cm cube find its total surface area if its height is 77cm​

Answer 1

Answer:

the answer is 27,468.571cm^2

Answer 2

Answer:

Volume =47432cm cube

Height =77cm

Volume =》

$\pi \: r {}^{2} {h }^{}$

$vol = \pi \: r {}^{2} h \\ = 47432 = \frac{22}{7} \times r {}^{2} \times 77 \\ = \frac{47432 \times 7}{22 \times 77} = r {}^{2} \\ = r {}^{2} = 196 \\ = r = \sqrt{196} \\ = r = 14$

Total surface area =

$\pi \: r(h + r)$

$total \: surface \: area = \pi \: r(h + r) \\ = \frac{22}{7} \times 14(77 + 14) \\ = 44 \times 91 \\ 4004cm {}^{2}$

hope IT HELPs....
