${ \red{ \bf{Don't \: Spam}}}\ \textless \ br /\ \textgreater$
Please solve the 6th one. ​

Answer 1

Given:-

• Radius of cylinder=5cm
• Total surface area of cylinder=660cm²

To find:-

• Height of the cylinder.

Sólution:-

• Let the height and radius be h and r respectively.

Now:-

T.S.A of cylinder is given by=2πr(r+h)u²

Therefore:-

$→2\pi r(r + h) = 660$

$→2 \times \frac{22}{7} \times 5 \times (5 + h) = 660$

$→ \frac{220}{7} \times (5 + h) = 660$

$→(5 + h) = 660 \times \frac{7}{220}$

$→(5 + h) = 21$

$→h = 16$

• Hence height of the cylinder is 16cm
