Question

Match the following areas and volume for a cylinder of heigth '$h$' and radius '$r$'.

• A. $2\pi rh$
• B. $2\pi rh+2\pi r^2$
• C. $\pi r^{2}h$

Answer 1

Lateral Surface Area(LSA) of cylinder = Circumference $\times$ height
$=2\pi r\times h$
$=2\pi rh$

Total Surface Area(TSA) of Cylinder = $LSA+2\pi r^2$
$=2\pi rh+2\pi r^2$

Volume of Cylinder = Area of circle $\times$ height
Volume of Cylinder $=\pi r^2\times h$
Volume of Cylinder $=\pi r^{2}h$
