Aleksandr-060686 [28]

Step-by-step explanation:

CSA\: of \:cylinder = 2πrh\\TSA\: of\:cylinder = 2πr(r+h)\\By \: conditions,\\2πrh =\frac{2}{3}\times2πr(r+h)\\3h = 2\times(r+h)\\3h = 2r + 2h\\h = 2r\\Also,\\2πr(r+h) = 924\\2\times\frac{22}{7}\times  r(r+2r) = 924\\ \frac{44}{7} \times r(3r) = 924 \\ 3r^{2} = 924 \times  \frac{7}{44} \\ 3r² = 147\\r²=\frac{147}{3}\\r² = 49\\r=\sqrt{47}\\ r = 7\\h = 2 \times 7 = 14\\hence\:radius=7cm,\:height=14cm\\

AVprozaik [17]

Answer:

A

Step-by-step explanation:

Given

p² - 16 = 0 ( add 16 to both sides )

p² = 16 ( take the square root of both sides )

p = ± \sqrt{16} = ± 4

Thus solution is { - 4, 4 } → A
