Answer
The surface area of the cylinder is \( 14\pi^{2}r^{2} \).
Solution
Calculate or simplify the expression \( 2 \times \pi \times r^{2} \times 2 \times \pi \times 1 \times 3.5 \).
Simplify the expression by following steps:
- step0: Solution:
\(2\pi r^{2}\times 2\pi \times 1\times 3.5\)
- step1: Rewrite the expression:
\(2\pi r^{2}\times 2\pi \times 3.5\)
- step2: Multiply the terms:
\(14\pi r^{2}\pi \)
- step3: Multiply the terms:
\(14\pi ^{2}r^{2}\)
The surface area of the cylinder is given by the formula \( 2 \times \pi \times r^{2} \times 2 \times \pi \times 1 \times 3.5 \), which simplifies to \( 14\pi^{2}r^{2} \).

Simplify this solution Beyond the Answer
To find the surface area (SA) of a cylinder, you usually use the formula \( SA = 2\pi rh + 2\pi r^2 \) where \( r \) is the radius and \( h \) is the height. However, it looks like you've written an equation that seems to contain some extra elements. Based on your equation, this could use clarification on the values for \( r \) and \( h \). Have fun playing around with numbers! You can visualize it with a can or a water bottle; everything around us can be a practical teaching point for these math concepts. Try measuring and calculating the surface area of different cylindrical objects you find at home!
