The surface area of a cylinder can be calculated using the formula:
Surface Area = 2 * π * r^2 + 2 * π * r * h
where r is the radius of the cylinder and h is the height of the cylinder.
Given that the radius of the cylinder is 11 and the height is 13, we can substitute these values into the formula:
Surface Area = 2 * π * 11^2 + 2 * π * 11 * 13
Surface Area = 2 * π * 121 + 2 * π * 143
Surface Area = 242π + 286π
Surface Area = 528π
To get the decimal approximation, we can use the value of π as 3.14159:
Surface Area ≈ 528 * 3.14159
Surface Area ≈ 1657.094
Rounded to the nearest whole number, the surface area of the cylinder is 1657.
Find the surface area of the cylinder to the nearest whole number. The figure is not drawn to scale.
