Question

The surface area of a solid cylinder of radius 2.0 cm and height 10.0 cm is equal to (mm)2

Answer 1

Answer: Now first you understand what is the meaning of surface area it is total surface area

And the T. S. A

of cylinder is 2πr(r+h)

Now put the values given in the question, 2π×2(2+10)

2×22/7×2×12

48×22/7 = 150.85cm^

Now we have to convert cm to mm

So as we know 1cm =10mm

So 1mm=1/10cm

So, 1mm=150.85/10

Then the answer in mm is = 15.08mm^
