Suppose you decide to cut the wire into two pieces (not necessarily the same length) to shape into two circles. Write a function A ( x ) which models the total area of the two circles in terms of x , the length of one of the pieces of wire. (It may be helpful to use for a circle A = πr 2 and C = 2 πr ). Then find the length x that will minimize the total area.

Answers

Answer 1
Answer:

Answer:

2\pi r(r+rx)

Explanation:

Let the area of one circular side be given by the formula : A_(1)  = \pi r^(2)

However, the wire is a solid cylinder, then it means that the total area is 2 × \pi r^(2) =2\pi r^(2)

However, there is the surface area to consider. This is the curved area of the wire. This is given as:

A_(2)  = lb

The length is x.

The breadth is calculated as follows  - the length of the circle = \pi D = 2\pi r

Then the area = lb

                        =2\pi rx

Therefore, the total area is given as A_(1)  + A_(2)

                       = 2\pi r^(2) + 2\pi rx\n 2\pi r(r+rx)

How many parsecs can a particular person parse if a person could parse a particular parsec

Answers


A parsec is a unit of distance.  It's not something that a parson can parse.

Final answer:

A parsec is a unit of distance used in astrophysics to measure the distance between celestial objects. It is equal to 3.26 light-years or approximately 31 trillion kilometers.

Explanation:

A parsec is a unit of distance used in astrophysics to measure the distance between celestial objects. It is equal to 3.26 light-years or approximately 31 trillion kilometers. The concept of a parsec is based on stellar parallax, which is a method used to calculate distances to nearby stars.
