Find area and round to nearest thousandth

Mathematics
1 answer:
vesna_86 [32]4 years ago
3 0

Answer:

236.715 ft²

Step-by-step explanation:

The figure consists of the rectangle with sides 15 ft and 4 ft and two semicircles with diameter 15 ft (radius 7.5 ft).

The area of the rectangle is

A₁=15·4=60 ft²

The area of two semicircles together is the area of circle. Thus,

A₂=πr²=π·7.5²=56.25π≈176.715 ft²

The area of the figure is

A=A₁+A₂=60+176.715=236.715 ft²

An ocean front lot has a perimeter of 250 feet and an area of at least 2500 square feet. Write an inequality describing this sit
evablogger [386]

Answer:

So, the inequality is

x(125-x)\geq 2500

Step-by-step explanation:

Since, the shape of ocean front is rectangular

Let's assume length of rectangle is x feet

width of rectangle us y feet

we are given

An ocean front lot has a perimeter of 250 feet

so, we get

2x+2y=250

now, we can solve for y

x+y=125

y=125-x

now, we can find area

Area=xy

now, we can plug back y

Area=x(125-x)

an area of at least 2500 square feet

so, we get

x(125-x)\geq 2500

Find the net outward flux of f=a×r across any smooth closed surface in r3, where a is a constant nonzero vector and r=〈x,y,z〉
Paul [167]

Flux is zero since asked in \pi is 0\pi.

Flux is the presence of a pressure field in a detailed physical medium or the glide of electricity through a surface. In electronics, the term applies to any electrostatic field and any magnetic subject. Flux is depicted as "traces" in a plane that contains or intersects electric powered fee poles or magnetic poles.

The definition of flux is a flow of liquid from the body, or a regular movement or exchange. An instance of flux is diarrhea. An example of flux is an ever-converting list of the responsibilities of a particular process. regular or frequent alternate; fluctuation.

Flux is a go-platform computer program that adjusts a show's color temperature in keeping with vicinity and time of day, offering practical respite for the eyes. the program is designed to reduce eye stress at some stage in night-time use, supporting reducing the disruption of sleep patterns.

Our field is IR^3 be,

F= (bz-cy,cx-az,ay-bx)

Now divergence theorem says that Flux can be calculated by

\int\limits^ {} \, F.n = \int\limits^ {} \,( c.F) dv

Now let's calculate the divergence of a vector field

F = (ia/ax + ja/ay + k*a/az)*((bz-cy)i+((x-dz))+(ay-bx)*k)

a/ax(bz-cy)+a/ay(cx-az)+a/az(ay-bx)

= 0+0+0

=0

Flux is zero since asked in \pi is 0\pi.
