Question

if CSA of right circular cylinder is 1100meter square and it's height is 25 meter, find the TSA of cylinder​

Answer 1

Step-by-step explanation:

To Find :

• we need to find the Total surface area of cylinder.

Solution :

• height of cylinder = 25m
• CSA of cylinder = 1100m²

$\boxed{{\underline{\blue{\textbf{CSA of cylinder = 2πrh:-}}}}}$

1100 = 2πr × 25

1100 = 50πr

1100/50 = πr

22× 7/22 = r

r = 7

$\boxed{{\underline{\blue{\textbf{TSA of cylinder = 2πr(r + h)}}}}}$

= 2× 22/7 × 7(7 + 25)

= 44(32)

= 1408 m²

$\large\dag \large { \red{\underline{\bf{Hence }}}}$

$\green{\textrm{ TSA of cylinder is 1408m² }}$
