Answer 2

Answer:

2.23 cm is the diameter of the cylinder.

Step-by-step explaination:

As the cylinder is cast from the rectangular piece,

surface area of the cylinder=surface area of the rectangle

2πrh=5×7×12

2×22/7×r×60=5×7×12

r=(5×7×12×7)/(2×22×60)

=49/44 cm

therefore, diameter=49/44×2cm

=49/22cm

=2.23 cm
