What is the surface area of the cylinder with height 6 ft and radius 6 ft? Round your
Paul [167]

The surface area of this cylinder to the nearest thousandth is equal to 452.448 square feet.

<u>Given the following data:</u>

  • Height of cylinder = 6 ft.
  • Radius of cylinder = 6 ft.

To calculate the surface area of this cylinder to the nearest thousandth:

<h3>How to calculate surface area.</h3>

Mathematically, the surface area (SA) of a cylinder is given by this formula:

SA = 2\pi rh + 2\pi r^2

<u>Where:</u>

  • h is the height.
  • r is the radius.

Substituting the given parameters into the formula, we have;

SA = 2 \times 3.142 \times 6 \times 6  + 2 \times 3.142 \times 6^2\\\\SA = 226.224 + 226.224

SA = 452.448 square feet.
