If a circle has circumference c, what is it’s are in terms of C
Scilla [17]
\text {Circumference = } 2 \pi r

c = 2 \pi r

\text {r = }  \dfrac{c}{2 \pi }


\text {area = }  \pi r^2

Sub r into area:

\text {area = } \pi ( \dfrac{c}{2 \pi } )^2

\text {area = }  \dfrac{\pi c^2}{4 \pi^2 }

\text {area = }  \dfrac{\ c^2}{4 \pi }

Alma invests $300 in an account that compounds interest annually. After 2 years, the balance of the account is $329.49. To the n
-Dominant- [34]

Invested amount (P) = $300.

Time in years (t) = 2 years.

Balance after 2 years (A) = $329.49.

Let us assume rate of interest = r % compounds annually.

We know, formula for compound interest

A=P(1+r)^t

Plugging values in formula, we get

329.49=300(1+r)^2

\mathrm{Divide\:both\:sides\:by\:}300

\frac{300\left(1+r\right)^2}{300}=\frac{329.49}{300}

\left(1+r\right)^2=1.0983

Taking square root on both sides, we get

1+r=\sqrt{1.0983}

\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}

1+r-1=\sqrt{1.0983}-1

r=\sqrt{1.0983}-1

r=1.048-1

r=0.048.

Converting it into percentage by multiplying by 100.

r=0.048 × 100

r  = 4.8 %

Therefore, the rate of interest on the account is 4.8% compounds annually.
