1²+3³+5²+....17²
= 1+9+25+49+81+121+169+225+289
= 969
Therefore, the required value is 969.

The possible numbers are:
206, 216, 226, 236, 246, 256, 260, 261, 262, 263, 264, 265, 266, 267, 268, 269, 276, 286, 296
Therefore, the digit 6 appears 20 times.

Given that,
A = 2³×3² and B = 2⁷×3⁵ 
Now,
A×B = 2³×3²×2⁷×3⁵
= 2³⁺⁷ × 3²⁺⁵
= 2¹⁰ × 3⁷

Given that,
A, B and C together can completely fill a tank in 45 minutes.
B and C together can fill the same tank in 6060 minutes.
Now,
1/A + 1/B + 1/C = 1/45
1/B + 1/C = 1/60
1/A = 1/45 - 1/60
⇒ 1/A  = (4-3)/180
⇒ 1/A = 1/180
⇒ A = 180
Therefore, A alone can fill the tank in 180 minutes.

∵ Volume of cylinder = πr²h
Ratio of volumes of both cylinder
= πr₁²h/πr₂²h
= (1/4)²
= 1/16
Therefore, the ratio of the volume of the two cylinders are 1:16.
