Answer:

Area of a circle = πr^2 if pi here = 3

then (3 × 81) in^2 = 243 in^2

Hope it helps

Answer:

The area of circle is 254.34 in².

Step-by-step explanation:

Given :

To Find :

Using Formulas :

[tex]\star{\small{\underline{\boxed{\sf{\pink{R = \dfrac{D}{2}}}}}}}[/tex]

[tex]\star{\small{\underline{\boxed{\sf{\pink{Area_{(Circle)} = \pi{r}^{2} }}}}}}[/tex]

Solution :

Here we have given that diameter of circle is 18 in. So, finding the radius of circle :

[tex]\implies{\sf{Radius = \dfrac{D}{2}}}[/tex]

[tex]\implies{\sf{Radius = \dfrac{18}{2}}}[/tex]

[tex]\implies{\sf{Radius = \cancel{\dfrac{18}{2}}}}[/tex]

[tex]\implies{\sf{Radius = 9 \: in}}[/tex]

[tex]\star{\underline{\boxed{\sf{\red{Radius = 9 \: in}}}}}[/tex]

Hence, the radius of circle is 9 in.

[tex]\rule{200}2[/tex]

Now, we know the radius of circle is 9 in. So, finding the area of circle by substituting the values in the formula :

[tex]\implies{\sf{Area_{(Circle)} = \pi{r}^{2}}}[/tex]

[tex]\implies{\sf{Area_{(Circle)} = 3.14\times {(9)}^{2}}}[/tex]

[tex]\implies{\sf{Area_{(Circle)} = 3.14\times {(9 \times 9)}}}[/tex]

[tex]\implies{\sf{Area_{(Circle)} = 3.14\times (81)}}[/tex]

[tex]\implies{\sf{Area_{(Circle)} = \dfrac{314}{100} \times 81}}[/tex]

[tex]\implies{\sf{Area_{(Circle)} = \dfrac{314 \times 81}{100}}}[/tex]

[tex]\implies{\sf{Area_{(Circle)} = \dfrac{25434}{100}}}[/tex]

[tex]\implies{\sf{Area_{(Circle)} = 254.34 \: {in}^{2} }}[/tex]

[tex]{\star{\underline{\boxed{\sf{\red{Area_{(Circle)} = 254.34 \: {in}^{2}}}}}}}[/tex]

Hence, the area of circle is 254.34 in².

Answer:

|x| - 17 = 0

Step-by-step explanation:

Step-by-step explanation:

[tex] { \cot^{2}x}(1 + \tan^{2}x) \\ = \frac{1}{ \tan^{2}x} (1 + \tan^{2}x)[/tex]

[tex] = \frac{1}{ \tan^{2}x } + 1[/tex]

[tex] = \frac{ \cos^{2} x }{ \sin^{2}x } + 1 = \frac{ \cos^{2}x + \sin^{2}x}{ \sin^{2} x } [/tex]

[tex] = \frac{1}{ \sin^{2}x } = \csc^{2} x[/tex]

[tex]\frac{29}{50}[/tex]

Step-by-step explanation:

[tex]\frac{29}{50}[/tex] put into decimal form is 0.58 (aka 58%)

The person above me was correct but didn't have the answer in fraction form.

The probability that a randomly chosen person on the bus is an adult chaperone or a male student is 0.58.

We have the following data -

On a field trip there are 6 adult chaperones, 21 female students, and 23 male students on a bus.

We have to find the probability that a randomly chosen person on the bus is an adult chaperone or a male student.

The formula to calculate the probability of an event is -

P(A) = n (A) / n(S)

Where -

n(A) - Number of favorable outcomes.

n(S) - Number of elements in the sample space.

In the question given to us, we have -

n (A) = favorable outcomes = 23 + 6 = 29

n (S) =  Elements in the sample space 23 + 21 + 6 = 50

Hence, the probability that a randomly chosen person on the bus is an adult chaperone or a male student is -

P(A) = [tex]\frac{n(A)}{n(S)}[/tex] = [tex]\frac{29}{50}[/tex] = 0.58

Hence, the probability of choosing will be 0.58.

Answer:

4

Step-by-step explanation:

The numbers you have are 2, 2, 3, 4, 8, 8, 8

First, cross out 2 on the very left and 8 on the very right.

Then you are left with 2, 3, 4, 8, 8, Then cross out the 2 on the left and the 8 on the right, and you are left with 3, 4, 8. Cross out the 3 and 8, and you are left with the median, 4.

Answer: 6% decrease

Step-by-step explanation:

Answer:

6% decrease

Step-by-step explanation:

Given that,

Initial number of students = 1200

At the end of the year there were 1128 students

We need to find the  percent of  change in enrollment.

Change in enrollment = 1200 - 1128 = 72

The percentage of change is :

[tex]\%=\dfrac{\text{change in students}}{\text{initial students}}\times100\\\\\%=\dfrac{72}{1200}\times 100\\\\=6\%[/tex]

So, there is a decrease of 6% in number of students.

Answer:

400cm²

Step-by-step explanation:

Total surface area of a prism includes the area of the top and bottom triangle sides of the prism, plus the area of all 3 rectangular sides.

Base & Bottom triangle area: 2 x [(8 x 15)/2] = 120cm²

Side triangle area: 17 x 7 + 8 x 7 + 15 x 7 = 280cm²

Total surface area = 280 + 120 = 400cm²

Answer:

The frame would cost $88

Step-by-step explanation:

The problem is asking for the perimeter basically. The formula to find the perimeter is P = 2l + 2w. So plug in 5 where there is a 'w' and plug in 6 where there is a 'l'.

22= 10+12    

Now that you have the perimeter, you'll have to find the cost of the frame. Just multiply 22 by the 4 dollars to get your answer.

Answer:

d. 3x - 1.

Step-by-step explanation:

45x^4−5x^2

The GCF is 5x^2 so we have:

5x^2(9x^2 - 1)

The expression in the parentheses is the difference of 2 squares so:

= 5x^2(3x - 1)(3x + 1)

Step-by-step explanation:

Mean= add all of the terms together and divide by the amount of terms

median= put all the terms in order and the middle number is the median

mode= the value the appears the most frequently

(A)

Step-by-step explanation:

Multiply both sides by (x + 3)(x - 3)

4(x + 3) + 2 = (x- 3)

4x + 12 + 2 = x - 3

3x = - 17

or

x = -17/3
