Area = Pi * r^2
'
r = 7 / 2 = 3.5

area = 3.14 * 3.5^2
area = 3.14 * 12.25
area = 38.465 m sq

How to find compound rate from given values, 10 years after, and initial
dybincka [34]

The formula that calculates the compound rate from the given values is r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})

<h3>How to determine the compound interest rate?</h3>

The compound interest formula is:

I = P(1 + \frac rn)^{nt} - P

Where:

  • P represents the principal amount
  • r represents the compound interest rate
  • n represents the number of times the interest is compounded
  • t represents the time in years
  • I represents the interest

We start by adding P to both sides

P + I = P(1 + \frac rn)^{nt}

Divide through by P

\frac{P + I}{P} = (1 + \frac rn)^{nt}

Take the nt-th root of both sides

\sqrt[nt]{\frac{P + I}{P}} = 1 + \frac rn

Subtract 1 from both sides

-1 + \sqrt[nt]{\frac{P + I}{P}} = \frac rn

Multiply through by n

r = n(-1 + \sqrt[nt]{\frac{P + I}{P}})

In this case, t = 10

So, we have:

r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})

Hence, the formula that calculates the compound rate is r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})

Jacob makes a scale drawing for a crate with a scale factor of 1:20. The dimensions of his scale drawing are 3 inches long by 2
kipiarov [429]

Answer: 6 inches long and 4 inches wide

Step-by-step explanation: The dimensions of the actual crate are 20 times those on Jacob's drawing. The dimensions on the builder's drawing are 1/10 of those, so (1/10)(20) = 2 times the dimensions on Jacob's drawing.
