Question

find the CSA of a cylinder with radius 3.5 cm and height 2.5 cm​

Answer 1

Answer:

$\huge \mathtt 55 \: {cm}^{2}$

Step-by-step explanation:

GIVEN :

r = 3.5 cm

h = 2.5 cm

We know that,

$\large \color{skyblue} \mathtt{CSA \: of \: cylinder = 2 π r h }$

$\large \mathbb{ = 2 × \frac{22}{7} × \frac{7}{2} × \frac{5}{2} }$

Cancelling out,

$\large{ \: \: = 11×5}$

= 55 sq cm
