STEP 1: find base area $ AB $

To find base area $ AB $ use formula:

$$ AB = r^2 \cdot \pi $$

After substituting $r = 1.21\, \text{cm}$ we have:

$$ AB = \left( 1.21\, \text{cm} \right)^{2} \cdot \pi $$ $$ AB = 1.4641\, \text{cm}^2 \cdot \pi $$

STEP 2: find Curved Surface Area $ CSA $

To find Curved Surface Area $ CSA $ use formula:

$$ CSA = l \cdot r \cdot \pi$$

After substituting $r = 1.21\, \text{cm}$ and $l = 3.8\, \text{cm}$ we have:

$$ CSA = 3.8\, \text{cm} \cdot 1.21\, \text{cm} \cdot \pi$$$$ CSA = 3.8\, \text{cm} \cdot 1.21\, \text{cm} \cdot \pi $$$$ CSA = 4.598\pi\, \text{cm}^2 $$

STEP 3: find area $ A $

To find area $ A $ use formula:

$$ A = AB + CSA $$

After substituting $AB = 1.4641\pi\, \text{cm}^2$ and $CSA = 4.598\pi\, \text{cm}^2$ we have:

$$ A = 1.4641\pi\, \text{cm}^2 + 4.598\pi\, \text{cm}^2 $$ $$ A = 1.4641\, \text{cm}^2 + 4.598\, \text{cm}^2 $$ $$ A = 6.0621\, \text{cm}^2 $$
