Find the area of the region between two concentric circular paths. If the radii of the circular paths are 210 m. and 490 m. resp
taurus [48]

Given :

  • The radii of the circular paths are 210 m. and 490 m.

To Find :

  • The area of the region between two concentric circular paths.

Solution :

Area of the outer circle :

\: \qquad  \dashrightarrow \sf{{ \pi \: \times  {(490)}^{2}  {m}^{2}}}

\: \qquad  \dashrightarrow \sf{{ \ \dfrac{22}{7} \times   \:490 \times 490 \:  {m}^{2}}}

\: \qquad  \dashrightarrow \sf{{ \ \dfrac{22}{ \cancel{7}} \times   \cancel{490} \times 490 \:  {m}^{2}}}

\: \qquad  \dashrightarrow \sf{{ \ {22} \times   70 \times 490 \:  {m}^{2}}}

\: \qquad  \dashrightarrow \bf{{ \ 754600 \:  {m}^{2}}}

⠀

Area of the inner circle :

\: \qquad  \dashrightarrow \sf{{ \pi \: \times  {(210)}^{2}  {m}^{2}}}

\: \qquad  \dashrightarrow \sf{{ \ \dfrac{22}{7} \times   \:210 \times 210 \:  {m}^{2}}}

\: \qquad  \dashrightarrow \sf{{ \ \dfrac{22}{ \cancel{7}} \times   \cancel{210} \times 210 \:  {m}^{2}}}

\: \qquad  \dashrightarrow \sf{{ \ {22} \times   30 \times 210 \:  {m}^{2}}}

\: \qquad  \dashrightarrow \bf{{ \ 138600 \:  {m}^{2}}}

⠀

Therefore,

Area of the region inside the circular paths :

\: \qquad  \dashrightarrow \sf{{ \ (754600 - 138600  )  \: {m}^{2}}}

\: \qquad  \dashrightarrow \bf{{ \ 616000 \:  {m}^{2}}}

The formula for computing compound interest for a principal P that is invested at an annual rate r and compounded annually is gi
maria [59]

9514 1404 393

Answer:

  • r ≈ 6%

Step-by-step explanation:

Solving for r when n=2, we have ...

  A=P(1+r)^2\\\\\dfrac{A}{P}=(1+r)^2\\\\\sqrt{\dfrac{A}{P}}=1+r\\\\\boxed{r=\sqrt{\dfrac{A}{P}}-1}

For the given values of A and P, the value of r is ...

  r=\sqrt{\dfrac{5600}{5000}}-1=\sqrt{1.12}-1\approx 1.0583-1\\\\\boxed{r\approx 6\%}

Which graph represents exponential decay?
xz_007 [3.2K]

Answer:

  (d) -- see attached

Step-by-step explanation:

A graph that shows exponential decay is one that tends toward a horizontal asymptote as x gets large.

__

A basic (parent) exponential decay curve is concave upward and tends toward zero as x gets large. The fractional change in any interval is the same as for any other interval of equal size. The curve attached decreases by a factor of 2 when x increases by 1.
