Answer:

A = 80π

Step-by-step explanation:

Area of a circle is A = πr²

Area of the the largest circle - Area of the smaller circle = the shaded part.

Largest circle    -    Area of the smaller circle   = Shaded part of circle

A  = π(12)²         -     A = π(8)²

    144π            -      64π                           =        80π

You are at a grocery store and the cost of your groceries is $32.75. You need to add the sales tax, which is 6%. You have one $2
schepotkina [342]

1. The total bill including sales tax is <u>$34.72</u>.

2. The amount the purchaser should pay the cashier is <u>$34.72</u>.

3. The denominations for the payment should be one $20 bill, one $10 bill, four $1 bills, and 72 cents (pennies).

<h3>How is the total cost determined?</h3>

The total cost payable to the grocery store cashier is the cost of the groceries plus the sales tax.

The cost for groceries = $32.75

Sales tax = 6%

Total cost = cost plus sales tax

= $34.72 ($32.75 x 1.06)

We can check the sum as follows:

Unit  Bill  Amount

1      $20    $20

1      $10       10

4       $1        4

Cents           0.72

Total        $34.72

Thus, the grocery purchaser will be spending <u>$34.72</u>, including the sales tax.

How do you know if 2 polygons are similar?
faltersainse [42]
Check the angles and corresponding sides: All the angles in a rectangle are congruent to each other and now check that the sides are proportional to each other. 2. Scale factor: If two polygons are similar, then the ratio of the lengths of the two corresponding sides is the scale factor.
