The surface area of a cylinder is calculated using the formula:
Surface Area = 2πr^2 + 2πrh
Where r is the radius of the base of the cylinder and h is the height of the cylinder.
Given that the radius of the cylinder is 13 and the height is 11, we can plug these values into the formula:
Surface Area = 2π(13)^2 + 2π(13)(11)
Surface Area = 2π(169) + 2π(143)
Surface Area = 338π + 286π
Surface Area = 624π
Approximating π to 3.14, we get:
Surface Area ≈ 624 x 3.14
Surface Area ≈ 1959.36
Rounding to the nearest whole number, the surface area of the cylinder is approximately 1959 square units.
Find the surface area of the cylinder to the nearest whole number. The figure is not drawn to scale.
