Answer:
The options are unclear but the answer is 8^2π square feet or 64π sqfeet
Explanation:
Area of a circle is denoted by: πr^2 where r is the radius of the circle.
In this question, the diameter was given. The diameter of a circle is twice the radius. Therefore, in order to get the radius, we divide the diameter by 2 i.e. r = d/2
= 16/2 = 8 feet.
Thus, the radius = 8 feet.
Hence, Area of a circle = πr^2
= π × 8^2
= 64π or 8^2π sqfeet.
The greenhouse effect influences climate by increasing the global temperature.
<h3>What is greenhouse effect?</h3>
The greenhouse effects are effects due to the presence of greenhouse gases in the atmosphere.
The greenhouse gases form a layer of gas in the atmosphere and prevent reflected solar radiation from escaping back into space. They, therefore, warm up the atmosphere by increasing the thermal energy.
As the concentration of the greenhouse gases in the atmosphere increases, so also is the amount of reflected solar radiation that is trapped in the atmosphere.
Therefore, an increase in greenhouse gas concentration increases the global temperature. Temperature influences other climatic factors such as precipitation.
Thus, the greenhouse effects influence climate by causing a rise in global temperature.

The last option because it's like the earth
The answer to this is Lipids, nucleic acids, proteins, glycerol and fatty acids.
Answer:
With an experiment following the scientific method
Explanation:
The basic steps of the scientific method are: 1) make an observation that describes a problem, 2) create a hypothesis, 3) test the hypothesis, and 4) draw conclusions and refine the hypothesis. Critical thinking is a key component of the scientific method. Without it, you cannot use logic to come to conclusions.
