Let the height be 'h' and radius be 'r'.
Given h + r = 37 cm
Total surface area of cylinder = 2πr(h+r) = 1628 cm²
2 x 22/7 x r x 37 = 1628 r = 7 cm
∴ h = 37 - 7 = 30cm
Given h + r = 37 cm
Total surface area of cylinder = 2πr(h+r) = 1628 cm²
2 x 22/7 x r x 37 = 1628 r = 7 cm
∴ h = 37 - 7 = 30cm

How r=7cm? plz show me
2*22=44
44*37= 1628. 1628 gets cancelled on both the sides. Multiply both the sides by 7. Now, you get r = 7cm
