The formula to calculate the surface area of a cylinder is:
Surface Area = 2πr(h + r)
Given:
Radius (r) = 4 cm
Height (h) = 2 cm
Using the approximation of π = 3.14, we can now calculate the surface area:
Surface Area = 2 * 3.14 * 4 * (2 + 4) (Simplify)
= 2 * 3.14 * 4 * 6
= 150.72 cm²
Therefore, the surface area of the cylinder is approximately 150.72 cm².

To find the surface area of a cylinder, you need to calculate the sum of the areas of the two bases and the lateral surface area.
Given:
Diameter (d) = 12 inches
Radius (r) = d/2 = 12/2 = 6 inches
Height (h) = 10 inches
Pi (π) ≈ 3.14
The formula for the surface area of a cylinder is:
Surface Area = 2πr^2 + 2πrh
Calculating the two base areas:
Base Area = πr^2
= 3.14 * (6 inches)^2
= 3.14 * 36 square inches
≈ 113.04 square inches
Calculating the lateral surface area:
Lateral Surface Area = 2πrh
= 2 * 3.14 * 6 inches * 10 inches
= 376.8 square inches
Calculating the total surface area:
Surface Area = 2πr^2 + 2πrh
= 2(113.04 square inches) + 376.8 square inches
= 226.08 square inches + 376.8 square inches
= 602.88 square inches
Therefore, the surface area of the cylinder is approximately 602.88 square inches.
Given:
Diameter (d) = 12 inches
Radius (r) = d/2 = 12/2 = 6 inches
Height (h) = 10 inches
Pi (π) ≈ 3.14
The formula for the surface area of a cylinder is:
Surface Area = 2πr^2 + 2πrh
Calculating the two base areas:
Base Area = πr^2
= 3.14 * (6 inches)^2
= 3.14 * 36 square inches
≈ 113.04 square inches
Calculating the lateral surface area:
Lateral Surface Area = 2πrh
= 2 * 3.14 * 6 inches * 10 inches
= 376.8 square inches
Calculating the total surface area:
Surface Area = 2πr^2 + 2πrh
= 2(113.04 square inches) + 376.8 square inches
= 226.08 square inches + 376.8 square inches
= 602.88 square inches
Therefore, the surface area of the cylinder is approximately 602.88 square inches.

I apologize for the incorrect response. Let's recalculate the surface area.
Given:
Diameter (d) = 12 inches
Radius (r) = d/2 = 12/2 = 6 inches
Height (h) = 10 inches
Pi (π) ≈ 3.14

Surface Area = 2πr^2 + 2πrh

= 113.04 square inches
Calculating the lateral surface area:
Lateral Surface Area = 2πrh
= 2 * 3.14 * 6 inches * 10 inches
= 376.8 square inches
Calculating the total surface area:
Surface Area = 2πr^2 + 2πrh
= 2(113.04 square inches) + 376.8 square inches
= 226.08 square inches + 376.8 square inches
= 602.88 square inches
