Help me find the answer
expeople1 [14]

Answer:

D. $16.42

Step-by-step explanation:

In order to find the sales tax of a product, you need to multiply the product's price by the sales tax in decimal form.

To find the decimal form of a percentage, you simply move the decimal paint two spaces to the left. So, 8.25% in decimal form is 0.0825.

199.99 * 0.0825 = 16.499175

This number is closest to $16.42, so D is the correct answer.

A square has a side that measures 55 units. What is the area of a circle with a circumference that equals the perimeter of the s
Taya2010 [7]
<h3><u>Given</u>:-</h3>

\rightarrow Side of square = 5.5 units.

\rightarrow Circumference of circle = perimeter of square.

<h3><u>To Find</u>:-</h3>

\rightarrow Area of circle.

<h3><u>Solution</u>:-</h3>

\rightarrow To find the area of circle firstly we have to find the perimeter of the square, then we will find the radius of circle and after that area of circle. So, let's begin:

\rightarrow Perimeter of square = \sf{4×side}(putting the value of side from the above given)

\rightarrow \sf{=\: 4 × 5.5}

\rightarrow \sf{=\: 22units.}

Therefore, perimeter of square = 22units.

Now, according to the question, perimeter of square = circumference of the circle. So, circumference of circle = 22units.

Now, using the formula of circumference of circle we can find the radius.

\rightarrow Circumference of circle = \sf{2πr}(putting the value of perimeter)

\rightarrow \sf{22\:=\: 2×3.14×r}

\rightarrow \sf{22\:=\: 6.28×r}

\rightarrow \sf{\frac{22}{6.28}\:=\: r}

\rightarrow \sf{3.50units\:=\: r}

Therefore, radius of circle = 3.50units.

Now, let's find area of the circle:

\rightarrow Area of circle = \sf{πr^2}

\rightarrow \sf{πr^2}(putting the value of pie(π) and radius(r))

\rightarrow \sf{3.14×3.50^2}

\rightarrow \sf{3.14×12.25}

\rightarrow \sf{38.46unit^2}

Therefore, area of circle = \sf{38.46unit^2}
