mario62 [17]

Answer:

The area of the shaded region is   329.87\ cm^2

Step-by-step explanation:

<u><em>The correct question is</em></u>

A circle with radius of 4cm sits inside a circle with a radius of 11cm. What is the area of the shaded region?

The shaded region is the area outside the smaller circle and inside the larger circle

we know that

To find out the shaded region subtract the area of the smaller circle from the area of the larger circle

so

A=\pi r_a^{2} -\pi r_b^{2}

simplify

A=\pi (r_a^{2} -r_b^{2})

where

r_a is the radius of the larger circle

r_b is the radius of the smaller circle

we have

r_a=11\ cm\\r_b=4\ cm

substitute

A=\pi (11^{2} -4^{2})

A=\pi (105)\ cm^2

assume

\pi=3.1416

substitute

A=(3.1416)(105)=329.87\ cm^2

5. You deposit $300 in an account Urat pays 1.48% annual interest. What is the balance after 1 year if the
kirill [66]

Answer:

The correct option is (A) $304.47.

Step-by-step explanation:

The formula to compute the future value (<em>FV</em>) of an amount (A), compounded daily at an interest rate of <em>r</em>%, for a period of <em>n</em> years is:

FV=A\times [1+\frac{r\%}{365}]^{n\times 365}

The information provided is:

A = $300

r% = 1.48%

n = 1 year

Compute the future value as follows:

FV=A\times [1+\frac{r\%}{365}]^{n\times 365}

      =300\times [1+\frac{0.0148}{365}]^{365}\\\\=300\times (1.00004055)^{365}\\\\=300\times 1.014911\\\\=304.4733\\\\\approx \$304.47

Thus, the balance after 1 year is $304.47.

The correct option is (A).

Viruses and viral videos portfolio help
alexdok [17]
Care to elaborate, what I can say right now is just that a virus is a malicious program that invades your computer and multiplies itself across several programs and folders. a viral video is only similar because it becomes really popular across the internet and "spreads" throughout the internet by fame. hope that help... oh and id say this is more of a computers question.

Goshia [24]

Answer:

Step-by-step explanation:

a) A diameter is a line that cuts a circle through at the centre. Line AD is a diameter.

Radius is half of a diameter i.e AD/2 = AO or OD

Chord is a straight line that touches the circumference of a circle. It doesn't pass through the centre like the diameter but cuts through the segments of a circle. Example of a chord is line FH

A tangent is a line that touches the circumference of a circle at just a point. It can touch any point on the circle. Example of a tangent line are AB and DE.

b) We must know that angle at a point or in a circle is 360°.

<EOH + <ECH = 360°

If <EOH = 131°

<ECH = 360° - 131°

<ECH = 229°

- <EFH falls in the circumference of the circle. Also know that, angle at the centre of a circle is twice angle at the circumference. Since <EOH is at the centre of the circle. <EFH = <EOH/2

<EFH = 131/2

<EFH = 65.5°

c) Given AB = DE, then <AB = <DE (oppositely directed angle).

Given <AOB = 20° then <DE = 20°

d) According to the diagram, <GFD = <GLD

If <GFD = 126°, then <GLD = 126°

e) Given HK = x+4, FK = x+14, GK = x, CK = x+32

From the diagram, CG = CK + KG

CG = x+32+x

CG = 2x+32

Also, FH = FK+HK

FH = x+14+x+4

FH = 2x+18
