The area of flying disk is 452.16 square centimeters

Step-by-step explanation:

The disc is in circular shape so we will use the formulas for circle in this question.

Given

Circumference = C = 75.36 centimeters

We have to find the area of the disc for which we have to find the radius first.

Let r be the radius

Then

Circumference is given by:

C=2\pi r

putting the values

75.36 = 2*3.14*r\\75.36 = 6.28r

Dividing both sides by 6.28

\frac{6.28r}{6.28} = \frac{75.36}{6.28}\\r = 12\ cm

The area of circle is given by:

A = \pi r^2

Putting the values

A = 3.14 * (12)^2\\A = 3.14*144\\A =452.16\ cm^2

Hence,

The area of flying disk is 452.16 square centimeters

If a is a positive integer and b is a negative integer, which expression must be positive?
nydimaria [60]

So, let's solve all of them and see:

a - (-b) = a + b ⇒ can be either positive or negative, depending on the numbers

a + (-b) = a - b ⇒ can either be positive or negative, depending on the numbers

a * (-b) = a * (-b) ⇒ negative answer no matter what

a / (-b) = a / (-b) ⇒ negative answer no matter what


So the answer is:

<em>"None of the above"</em>.

Place the decimal point in the answer to make it correct. Explain your reasoning. 3.9853X8.032856 = 32013341.
horsena [70]
<span>1.       </span><span>The Given problem is to find where to place the decimal point to the product shown below.
3.9853 x 8.032856, notice that the given equation are decimal numbers with both ones place value of the whole number.
Now, given the answer 32013341 without decimal point, let’s find where to put the decimal point.
=> 3.9853 x 8.032856
=> 32.013341
Thus, the decimal point is now located after the 2nd number.  We now have 2 whole numbers with value of tens.

The picture shows a triangular island:
sergiy2304 [10]

Answer:

The expressions that show the value of q are

1) q=\sqrt{r^{2}+s^{2}}

2) q=\frac{s}{cos(55\°)}

3) q=\frac{r}{sin(55\°)}

4) q=\frac{s}{sin(35\°)}

5) q=\frac{r}{cos(35\°)}

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

case A)

In the right triangle of the figure

Applying the Pythagoras Theorem

q^{2}=r^{2}+s^{2}

q=\sqrt{r^{2}+s^{2}}

case B)

In the right triangle of the figure

cos(55\°)=\frac{s}{q}

solve for q

q=\frac{s}{cos(55\°)}

case C)

In the right triangle of the figure

sin(55\°)=\frac{r}{q}

solve for q

q=\frac{r}{sin(55\°)}

case D)

In a right triangle

if A+B=90\°

then

cos(A)=sin(B)

therefore

q=\frac{s}{cos(55\°)}------> q=\frac{s}{sin(35\°)}

q=\frac{r}{sin(55\°)} ------>  q=\frac{r}{cos(35\°)}
