2 πR² + 2 π R H = TSA = 1628 cm²
2 π R (R + H ) = 1628
R = 1628 / (2 π * 37 ) = 7 cm

H = 30 cm

V = π R² H = 1470 π cm³

Let, radius of cylinder be x , height of cylinder = (37-x) [ sum of radius and height of cylinder is 37 ] | Tsa of cylinder =2πr(h+r), 1628 = 2×22÷7×x(37-x+x), 1628 = 2×22÷7×37x, (1628×7) ÷(2×22×37) = x, x = 7, Radius of cylinder = 7, Height of cylinder = (37-x), = (37-7), = 30, Volume of cylinder = πr×r×h, = 22÷7×7×7×30, = 22×7×30, = 154×30, Volume of cylinder = 4620 cm cube
