Answers
GPT 3.5
The formula to calculate the surface area of a cylinder is 2πr(r + h), where r is the radius and h is the height.
Given:
Radius (r) = 8 in
Height (h) = 4 in
Substitute the values into the formula:
Surface area = 2π(8)(8 + 4)
Surface area = 2π(8)(12)
Surface area = 2π(96)
Surface area ≈ 602.88 square inches
Therefore, the surface area of the cylindrical cylinder is approximately 602.88 square inches.
