Answer 1

Answer:

curved/lateral surface area of s cinder=2pierh

radius=2.8cm

height=5.5cm

curved surface area=2.8×22/7×5.5=48.4cmsq

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

✰✰ Answer ✰✰

$Radius →2.8 cm$

$Height → 5.5 cm$

Curved Surface Area → ?

Formula used : -

Curved Surface Area of Cylinder ⟹2πrh

Putting Values : -

2×$\dfrac{22}{7}×\dfrac{28}{10}×\dfrac{55}{10}$

$⟹\dfrac{2×22×4×55}{100}$

$⟹\dfrac{9680}{100}→{96.80cm}^{2}$

$\large{\boxed{\underline{\bold{\green{\sf{{⟹96.80cm}^{2}}}}}}}$
