Question

if the radius of the base of a cylinder is 14cm and height is 30cm. find its CSA​

Answer 1

$\huge\bold{\gray{\sf{Answer:}}}$

$\bold{Explanation:}$

Given:

Radius of cylinder is 14 cm

Height of the cylinder =40cm

To Find :

Curved surface area of cylinder

=>Curved surface area is the area of Edge of a solid figure excluding the top and base parts.

Curve surface area =$\sf2\pi \: rh$

$\sf= > 2 \times \dfrac{22}{7} \times 14 \times 30$

$\sf= > \dfrac{44}{7} \times 14 \times 30$

$\sf= > 44 \times 2 \times 30$

$\sf= > 2640 {cm}^{2}$

$\therefore$ CSA of cylinder is $\bold{\purple{2640 {cm}^{2} }}$

Other Formulas for Cylinder=>

Total Surface Area=$\sf2\pi \: rh(h + r)$

Volume of Cylinder =$\sf \pi {r}^{2} h$
