To find the surface area of a cylinder, you can use the formula:
\[ \text{Surface Area} = 2\pi r(h + r) \]
where:
- \( r \) is the radius of the cylinder,
- \( h \) is the height of the cylinder, and
- \( \pi \) is approximately 3.14.
Given:
- Radius (\( r \)) = 4 cm
- Height (\( h \)) = 2 cm
Substituting these values into the formula:
\[ \text{Surface Area} = 2 \times 3.14 \times 4 \times (2 + 4) \] \[ = 2 \times 3.14 \times 4 \times 6 \] \[ = 2 \times 3.14 \times 24 \] \[ = 2 \times 75.36 \] \[ = 150.72 \text{ cm}^2 \]
So, the surface area of the cylinder is approximately 150.72 cm².
