Answer:

All of them cause pollution

Step-by-step explanation:

  • Car exhaust: it causes air pollution due to the release of certain dangerous forms of carbon into the atmosphere.
  • Chemicals:this causes a wide range of effects as it can lead to air water and land pollution. Its effects ranges from release of harmful gases into the atmosphere to pollution of river to the contamination of soil
  • Oceans: this can be caused when water is not needed in a particle environment and this water can lead to the contamination of those materials in that environment as in the case of a chemical experiment that gets contaminated or becomes dangerous when exposed to moisture or the direct entry of ocean water into a habitat that doesn't need that much water
  • People: They can be see as the major cause as the control or affect what goes wrong in their environment. They have certain control on various factors that cause pollution.

Find the lateral area of the cylinder. Give your answer in terms of pi
Artist 52 [7]

Answer:

<h2>204π units²</h2>

Step-by-step explanation:

The lateral area of the cylinder includes both the side and the ends.

The area of the side can be found by calculating the circumference of the cylinder and multiplying that by the height:  A = 2π(6 units )(11 units) = 132π units².

The area of one end of this cylinder can be found by applying the "area of a circle" formula:  A = πr².  Here, with r = 6 units, A = π(6 units)² = 36π units².  Since the cylinder has two ends, the total area of the ends is thus 2(36π units) = 72π units.

The total lateral area of the cylinder is thus 72π units² + 132π units², or 204π units²
