Answer: 1133.54

Step-by-step explanation:

The formula to find the area of a circle is \pi times the radius squared. The radius here is 19 so in order to square 19 you have to do 19x19 which is 361. Then, just multiply 361 by 3.14 and you should get 1133.54 as your final answer. Hope this helps!

Evaluate. 72 - 3 + 9 × 8 ÷ 2 w =
d1i1m1o1n [39]

Answer:

Step-by-step explanation:

Request of activities so increase then division, at that point deduction and expansion.  

9*8 = 72  

72/2 = 36  

72-3 = 69  

69+36 = 105

Another way of saying it is:

Utilize the request for tasks to improve on mathematical articulations. The request is brackets, types and roots, augmentation and division, expansion and deduction. Duplication and division are "something similar" so you would utilize the first that happens from left to right.  

Bit by bit clarification:  

7^2 - 3 + 9 x 8 ÷ 2  

49 - 3 + 9 x 8 ÷ 2  

49 - 3 + 72 ÷ 2  

49 - 3 + 36  

49 - 39  

W=10

Graph the following equations on the graphs below. <br> ( GRAPHING PAPER NEEDED, NOT A WEBSITE )
kodGreya [7K]

First, you want to identify the slopes and y-int.

Equation 1 = y = -2x + 2

Slope = -2

y-int. = 2 or (0,2)

Equationt 2 =  y = 2x + 3

Slope = 2

Y-int.  = 3 or (0,3)

To graph, first plot the y-intercepts. Then do the slopes.

Slope = -2

Down 2 over 1 (to the right)

Slope = 2

Up 2 over 1 (to the right)

Then just connect the dots in a line!

Solve the inequality 5(2h+8)&lt;60
zimovet [89]

Answer:

<h2>h < 2</h2>

Step-by-step explanation:

5(2h+8) < 60

Expand the terms in the bracket

We have

10h + 40 < 60

Group like terms

10h < 60 - 40

10h < 20

Divide both sides by 10

h < 2

Hope this helps you
