Answer:

2a). Height = 2 cm

2b). Surface area = 395.84 cm²

Explanation:

2a). Volume of the cylinder = 308 cm³

Radius of the base of the cylinder = 7 cm

Formula to get the volume of a cylinder = πr²h

308 = π(7)²h

h =
(308)/(49\pi )

h = 2 cm

Therefore, height of the cylinder will be 2 cm.

2b). Formula to calculate the surface area of the cylinder =
2\pi r(r + h)

By substituting the values in the given formula,

S.A. = 2π(7)(7 + 2)

= 395.84 cm²

Therefore, Surface area of the cylinder is 395.84 cm².
