Answer 1

Explanation:

The details given about cylindrical rod are –

Curved surface area of a cylindrical rod = 132 cm2

Length of radius = 0.35 cm

Let length of rod = h

Curved surface area of a cylinder = 2 * (22/7) * r * h

132 = 2 * (22/7) * 0.35 * h

(132 * 7)/(2 * 0.35 * 22) = h

h = 60 cm
