$\mathbb{\huge{\bigstar{\red{QuestioN}}}}{\huge{\bigstar}}$

✏A cylinder has 50cm diameter and height 4 mater. find the curved surface area ?

$\mathtt{\huge{\pink{Given}}}$

➡50cm diameter

➡4meter is height

$\mathtt{\huge{\purple{To\:Find}}}$

➡Curved surface area of the cylinder.

$\mathtt{\huge{\blue{Answer}}}$

➡6.68m²

$\mathtt{\huge{\green{Solution}}}$

➡Firstly unit conversion of diameter 50cm into m

✴diameter = 0.5m

➡formula:-

✴2 π $\frac{d}{2}$ h + 2 π $(\frac{d}{2})²$

= 2 π $\frac{0.5}{2}\times 4$ + 2 π $(\frac{0.5}{2})²$

➡6.67588m²

➡6.68m² (Approx value)
