The total surface area of a cylinder is the sum of the areas of its top and bottom circles, along with the area of its lateral surface (the curved surface that connects the two circles).
The formula for the lateral surface area of a cylinder is:
Lateral surface area = 2πrh
where r is the radius of the cylinder, h is the height of the cylinder, and π (pi) is a mathematical constant approximately equal to 3.14.
The formula for the area of a circle is:
Area of circle = πr^2
Using these formulas, we can calculate the total surface area of the cylinder as follows:
Area of top and bottom circles = 2 × π × r^2
= 2 × 3.14 × 2^2
= 25.12 square feet
Lateral surface area = 2 × π × r × h
= 2 × 3.14 × 2 × 6
= 75.36 square feet
Total surface area = Area of top and bottom circles + Lateral surface area
= 25.12 + 75.36
= 100.48 square feet
Therefore, the total surface area of the cylinder is 100.48 square feet.
