The area of the curved surface of a solid cylinder is equal to 2 by 3 of the total area of the same cylinder if the total surfac

Aleksandr-060686 [28]

Step-by-step explanation:

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

Drag each number to show whether it is equal to 2/10, 2/100, or neither.

Evgesh-ka [11]

Answer:

20/10 goes to neither since it equals 2

0.02 goes to 2/100 since it is the same as 0.02

200 goes to neither because it is over 2/10 and 2/100

0.20 goes to 2/10 since 2/10 is equal to 0.20

2.0 goes to neither because it equals 2

Hope this helped
