If a circle has a radius of 4. then the area of the circle is

Geography
1 answer:
saw5 [17]3 years ago
6 0

Answer

16\pi or 50.24 units

Explanation:

\pir^{2} and r is the radius, since we know what the radius is (<em>r </em>) we can put this in to an expression

\pi · 4² = 16 units

If the answer is not 16 then its 50.24 units

Explanation:

Now 16 is the correct answer but just in case I took this a step further.

If we estimate the area by using 3.14 which is ( \pi ) because sometimes that isn't  natural to express the area using \pi

I hope I helped you : )

What are some of the factors that contribute to a patients first impression of a healthcare facility?
kupik [55]
There could be several factors that would affect the first impression of an individual of the healthcare facility. These are listed below.
(1) cleanliness --> when a facility is cleaned, it means that it is well-managed and people are concerned about the rather unwanted effects of having a dirty workplace.

(2) price --> people tend to believe most of a time that facilities that ask for higher payment tend to have better quality of service and equipment.

(3) employees --> it is important that the employees inside the facility will be able to relate well to the admitted patients for them to feel comfortable and relaxed.

During the Soviet Era, the government had a great effect on agriculture. Do you believe that the system of agriculture was subsi
timofeeve [1]

Answer:

A combination.

Explanation:

The government mandated that most crops grown under Soviet rule would be given to the gov. to redistribute to people in need; however this caused great hunger and people started to farm on the side for substinence. Now hardcore socialists believe commercial farming is not applicable to government-takeover of crops, but I call it commercial since there was "compensation" to the farmers (not really lol).

Annette [7]

Answer:

Explanation below

Explanation:

Asia and the Pacific region have continued to remain the world's largest producer of fish. Various researchers have identified certain benefits of consuming seafood, which have caused greater demand for them. Apart from being ideal source of vitamins, fish is also rich in Omega 3 fatty acids, which can help prevent high blood pressure, cancer and heart diseases. Seafood also strengthen the immune system through their antioxidants.  

Rapid advances in fishing technology have led to the dramatic increase over the last 50 years in how many fish we are able to catch. Most people in the fishing business now use factory ships, in place of fishing vessels. These ships are can stay at the sea for several weeks and they have all the necessary equipment that can be used to either freeze of tin fish that they catch using their hunting ships.  

The factory ships need to get full before they can return to base and this has caused over a 7% growth in catches every year.

Bowen’s continuous reaction series describes the crystallization behavior of a singlemineral (with variable chemical composition
FromTheMoon [43]

Answer:

C. plagioclase

Explanation:

From the magma silicate crystals are formed successively when the magma temperature reaches the typical melting temperature for each type of crystal. The first crystals formed at high temperatures can then change their composition or dissolve again. In this way the crystals already formed contribute their ions, molecules and atoms to magma and combine again forming new crystals whose melting temperature is lower than that of the first crystals formed. The new crystals are said to be stable at the lowest temperatures set now. These processes of change are called reactions. As several successive reactions occur as the magma temperature decreases the ordered series of reactions is called the BOWEN series in honor of the Canadian scientist who formulated this concept. There are two types of reactions, the continuous reaction and the discontinuous reaction.

<u> By continuous reaction a crystal formed at high temperatures such as a plagioclase rich in the Ca2 +</u> component gradually varies its composition by replacing a portion of the Ca2 + ions with the Na + ions and a portion of the Al3 + ions with the Si4 + ions. To maintain its neutrality, the replacement of Ca2 + by Na + is coupled with the replacement of Al3 + by Si4 +. The series of continuous reaction starts from the plagioclase rich in Ca2 +, passes through several plagioclase of intermediate composition towards the plagioclase rich in Na +
