Answer 2

Answer:

4620 m³

Step-by-step explanation:

Let 'r' be the radius of base and 'h be the height of the cylinder.

Given, Sum of radius of base and height of cylinder is 37 m.

⇒ r + h = 37 cm   ---- (i)

Given, Total surface area of the solid cylinder is 1628 m².

⇒ 2πr(r + h) = 1628

⇒ 2πr(37) = 1628

⇒ 2 * (22/7) * r * 37 = 1628

⇒ 1628 * r = 1628 * 7

⇒ r = 7 m.

Substitute r = 7 in (i), we get

⇒ r + h = 37

⇒ 7 + h = 37

⇒ 30 m = h.

∴ Volume of the cylinder = πr²h

                                         = (22/7) * (7)² * 30

                                         = 4620 m³

Therefore, Volume of the cylinder = 4620 m³.
