Radius of Cylinder = 5 cm
Total surface area of cylinder = 2\pi r(h+r)2πr(h+r)
= 2 \times 3.14 \times 5(h+5)2×3.14×5(h+5)
Since we are are given that total surface area 660 cm sq
So, 660=2 \times 3.14 \times 5(h+5)660=2×3.14×5(h+5)
660=31.4(h+5)660=31.4(h+5)
\frac{660}{31.4}=h+5
31.4
660
=h+5
21.0191082803=h+521.0191082803=h+5
21.0191082803 -5=h21.0191082803−5=h
16.019=h16.019=h
Thus the height of the cylinder 16.019 cm.
