Question

A cylinder has a height of 16 cm and a diameter of 14 cm.

Calculate the surface area of the cylinder.
Give your answer to the nearest integer.

Answer 1

1011.59 cm^2

Explanation:

The formula for the surface area of a cylinder is:

Surface Area = 2πr(r + h)

Given that the radius (r) is 7 cm and the height (h) is 16 cm, we can substitute these values into the formula:

Surface Area = 2π(7 cm)(7 cm + 16 cm)

Calculating this:

Surface Area = 2π(7 cm)(23 cm)

Surface Area ≈ 1011.59 cm^2

Rounding this to the nearest integer, the surface area of the cylinder is approximately 1011.59 cm^2.
