Answer:

The area of the shaded region is 17.4 square meters.

Step-by-step explanation:

Since the shaded region in the center equals the remainders of a circle, the area of a square equals its side squared, and the area of a circle equals π times the radius squared, for To determine the area of the shaded region, the following calculations should be performed:

(9 ^ 2) - (π x (9/2) ^ 2) = X

81 - (π x 4.5 ^ 2) = X

81 - (3.141 x 4.5 ^ 2) = X

81 - 3.141 x 20.25 = X

81 - 63.6 = X

17.4 = X

Thus, the area of the shaded region is 17.4 square meters.

If $11,000 is invested in an account for 25 years. Find the value of the investment at the end of 25 years if the interest is:
Naya [18.7K]

If $11,000 is invested, $33,000 is the value of the investment at the end of 25 years if the interest is 8% simple interest and $75,333.23 is the value of the investment at the end of 25 years if the interest is 8% compounded annually. This can be obtained by using formulas for simple interest and compound interest.

<h3>What is the formulas of simple interest and compound interest?</h3>
  • Simple interest

A = P(1 +Rt/100) , P = principle amount ,R = rate of interest, t = time(in years)

  • Compound interest (annually)

A = P(1 + R/100)^t , P = principal amount, R = rate of interest,                                t = time(in years)

   

<h3>What is the value of investment?</h3>

Given that,  

P = $11,000 , R = 8%,  t = 25 years

  • 8% simple interest

A = P(1 +Rt/100) = 11000(1+\frac{(8)(25)}{100} ) = $33,000

  • 8% compounded annually

A = P(1 + R/100)^t = 11000(1+\frac{8}{100} )^{25} = 11000(1.08 )^{25} = $75,333.23

Hence If $11,000 is invested, $33,000 is the value of the investment at the end of 25 years if the interest is 8% simple interest and $75,333.23 is the value of the investment at the end of 25 years if the interest is 8% compounded annually.
