To find the surface area of the cylinder, we need to calculate the sum of the areas of the two circular bases and the lateral surface area.
The formula for the surface area of a cylinder is given by:
A = 2πrh + 2πr^2
Given that we should use the approximation 3.14 for pi, let's substitute the values:
A = 2(3.14)(7)(12) + 2(3.14)(7)^2
A = 2(3.14)(7)(12) + 2(3.14)(49)
A = 527.04 + 307.86
A ≈ 834.9
Rounded to the nearest whole number, the surface area of the cylinder is approximately 835 square centimeters.
