The formula for finding the surface area of a cylinder is:
\[ SA = 2\pi r^2 + 2\pi rh \]
Now, let's break down the formula and compute the surface area using \( \pi = 3.14 \). To do this, we need the radius (r) and height (h) of the cylinder. Since these values are not provided, I will give you the formula, and you can substitute the appropriate values.
Assuming you have the radius and height, you can follow these steps:
1. Calculate the area of the two circular bases:
\[ 2\pi r^2 \]
2. Calculate the area of the side (lateral surface area):
\[ 2\pi rh \]
3. Add the two areas together to get the total surface area:
\[ SA = 2\pi r^2 + 2\pi rh \]
If you provide the radius and height, I can help you further by calculating the exact surface area. The provided answers seem to suggest they have been calculated with specific values of r and h, so please share those values for an accurate calculation.
\[ SA = 2\pi r^2 + 2\pi rh \]
