STEP 1: find base area $ AB $
To find base area $ AB $ use formula:
$$ AB = r^2 \cdot \pi $$After substituting $r = 2\, \text{cm}$ we have:
$$ AB = \left( 2\, \text{cm} \right)^{2} \cdot \pi $$ $$ AB = 4\, \text{cm}^2 \cdot \pi $$STEP 2: find Curved Surface Area $ CSA $
To find Curved Surface Area $ CSA $ use formula:
$$ CSA = l \cdot r \cdot \pi$$After substituting $r = 2\, \text{cm}$ and $l = 3\, \text{cm}$ we have:
$$ CSA = 3\, \text{cm} \cdot 2\, \text{cm} \cdot \pi$$$$ CSA = 3\, \text{cm} \cdot 2\, \text{cm} \cdot \pi $$$$ CSA = 6\pi\, \text{cm}^2 $$STEP 3: find area $ A $
To find area $ A $ use formula:
$$ A = AB + CSA $$After substituting $AB = 4\pi\, \text{cm}^2$ and $CSA = 6\pi\, \text{cm}^2$ we have:
$$ A = 4\pi\, \text{cm}^2 + 6\pi\, \text{cm}^2 $$ $$ A = 4\pi\, \text{cm}^2 + 6\pi\, \text{cm}^2 $$ $$ A = 10\pi\, \text{cm}^2 $$
