Answer:

V = A ≈ 78.54 cm3 (E)

Step-by-step explanation:

Using the formulas above and additional formulas you can calculate the properties of a given circle for any given variable.

Calculate A, C, and d | Given r

Given the radius of a circle calculate the area, circumference and diameter. Putting A, C and d in terms of r the equations are:

A=πr2

C=2πr

d=2r

Calculate r, C, and d | Given A

Given the area of a circle calculate the radius, circumference, and diameter. Putting r, C, and d in terms of A the equations are:

r=Aπ−−√

C=2πr=2πAπ−−√

d=2r=2Aπ−−√

Calculate A, r, and d | Given C

Given the circumference of a circle calculate the radius, area and diameter. Putting A, r, and d in terms of C the equations are:

r=C2π

A=πr2=π(C2π)2=πC24π2=C24π

d=2r=2C2π=Cπ

Calculate A, C, and r | Given d

Given the diameter of a circle calculate the radius, area, and circumference. Putting A, C, and r in terms of d the equations are:

r=d2

A=πr2=π(d2)2=πd24

C=2πr=2πd2=πd

Five years ago, you invested $475 in corporate stock. You received dividends of $10 at the end of each quarter for two years. Yo

RUDIKE [14]

The rate of return earned on the investment of $475 five years ago in the corporate stock is 312.63%.

<h3>What is the rate of return?</h3>

The rate of return is the net gain or loss of an investment expressed as a percentage of the investment's initial cost.

It is given by the formula, R= {Vf - Vi}/{Vi} x 100.

Where:

R = Rate of return

Vf = final value, including dividends and interest

Vi = initial value

<h3>Data and Calculations:</h3>

Investment cost = $475

Dividends received:

1st two years = $80 ($10 x 8)

Three years = $180 ($15 x 12)

Total dividends received = $260 ($80 + $180)

Total revenue from sale = $1,700

Total proceeds = $1,960 ($1,700 + $260)

Total return = $1,485 ($1,960 - $475)

Rate of return = 312.63% ($1,485/$475 x 100)

Thus, the rate of return is 312.63%.

Multiply and simplify if possible. sqrt 5x(sqrt x-5 sqrt 5)

RSB [31]

Making the assumption that your problem looks like this,
$\sqrt{5x}(\sqrt{x}-5\sqrt{5})$

we use the distributive property to multiply:
$\sqrt{5x}\times \sqrt{x}-\sqrt{5x}\times5\sqrt{5}
\\
\\ \sqrt{5x^2} - 5\sqrt{25x}
\\
\\ x\sqrt{5}-25\sqrt{x}$
