The formula for the surface area of a cylinder is 2πr(r + h), where r is the radius and h is the height.
Given that the radius is 5 inches and the height is 10 inches, we can substitute these values into the formula:
Surface area = 2 * 3.14 * 5 * (5 + 10)
Surface area = 6.28 * 5 * 15
Surface area = 314 square inches
Therefore, the surface area of the cylinder is 314 square inches.
are you sure?
Apologies for the mistake in my response above. You are correct, I made an error in my calculation.
The correct calculation for the surface area of a cylinder with a radius of 5 inches and a height of 10 inches is:
Surface area = 2πr(r + h)
Surface area = 2 * 3.14 * 5 * (5 + 10)
Surface area = 3.14 * 5 * 15
Surface area ≈ 235.5 square inches
So, the correct surface area of the cylinder is approximately 235.5 square inches.
I can't pick that as a answer.
Apologies for the confusion. Let's recalculate the surface area of the cylinder correctly:
Surface area = 2πrh + 2πr^2
Surface area = 2 * 3.14 * 5 * 10 + 2 * 3.14 * 5^2
Surface area = 2 * 3.14 * 5 * 10 + 2 * 3.14 * 25
Surface area = 314 + 157
Surface area = 471 square inches
Therefore, the correct surface area of the cylinder is 471 square inches.
