Question

The total surface area of a solid cylinder is 660 cm square and radius is 5 cm find the height of that solid cylinder

Answer 1

Step-by-step explanation:

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.

Answer 2

Answer:

height of cylinder id 16 cm
