=452.16cm sq

The are of the smaller circle, r=6cm

=same formula

=3.14×6×6

=113.04cm sq

Subtract them to find the area of the shaded region

The final amount of the compound interest after 6 years would be $ 294, 122, 500

<h3>How to determine the final amount</h3>

The formula for the final amount is given as;

$A = P( 1 + \frac{r}{n}) ^n^t$

Where

A = final amount

P = principal interest

r = interest rate

n = number of times

t = time of periods

We have,

A = $2500$ $( 1 + \frac{6}{1}) ^1^*^6$

A = $2500 ( 7)^6$

A = $2500$ × $117, 649$

A =$ $294, 122, 500$

Thus, the final amount of the compound interest after 6 years would be $ 294, 122, 500

michelle hong noticed that her gross pay per period increased by 2,800 when her employer changed from a bi weekly pay plan to a

mart [117]

Answer:

Her annual salary is $62,400

Step-by-step explanation:

Michelle Hong noticed that her gross pay per period increased by 2,800 when her employer changed from a bi weekly pay plan to a monthly pay plan.

Bi weekly is a check every 2 weeks, so she would get 26 checks per year.

Monthly would be 12 checks per year.

When she gets paid monthly her pay increased by $2,800 each check.

Let x be one bi-weekly paycheck.

The equation we get is:

12(x+2800) = 26x

Multiply the bracket by 12:

12x +33600 = 26x

Subtract 12x from both sides

33600 = 14x

Divide both sides by 14:

x = 33600/14

x = 2400

Her pay increased by 2800 each period:

2400 + 2800 = 5200 per check.

5200 x 12 months = 62400

Her annual salary is $62,400
