How many feet does it take to make a 6 foot circle?

Mathematics

masha68 [24]3 years ago
6 0
This is the concept of perimeter of figures, to get the length of material that is required to make a circle with diameter 6 ft, we are required to calculate for its circumference;
circumference, C= π*diameter
C=3.14*6=18.85 ft
therefore it will take a material whose length is 18.85 ft to make a circle of 6 feet

Hello there! The formula for finding slope is y2 - y1 / x2 - x1, meaning you subtract the first x and y-coordinates, from the second x and y-coordinates. In this case, the formula would be set up as -2 - 5 / 2 -1, because (2, -2) is the second point and (1, 5) is the first point. The answer is C: 2 - 1.

Write the next three terms in the pattern. What is each pattern rule?<br><br> +6, -12, +18, -24, ...
natali 33 [55]

Answer: 30, -36, 42

Step-by-step explanation:

So basically the pattern is just the next number that is a multiple of six, but every other number is negative. 6 is 6 times 1, -12 is 6 times -2, 18 is 6 times 3, -24 is 6 times -4, 30 is 6 times 5, -36 is 6 times -6, and 42 is 6 times 7

6(x - 6) +2x = 6(2 - 3x) + 4x - 2x
gogolik [260]

Answer:

x=2

Step-by-step explanation:

6(x-6)+2x=6(2-3x)+4x-2x

6x-36+2x=12-18x+4x-2x

8x-36=-16x+12

24x-36=12

24x=48

x=2

Paul and jose are trying to measure the height of a tree. paul is standing 19m from the foot of the tree and measures the angle
Nina [5.8K]
The firts thig we are going to do is create tow triangles using the angles of elevation of Paul and Jose. Since the problem is not giving us their height we'll assume that the horizontal line of sight of both of them coincide with the base of the tree.
We know that Paul is 19m from the base of the tree and its elevation angle to the top of the tree is 59°. We also know that the elevation angle of Jose and the top of the tree is 43°, but we don't know the distance between Paul of Jose, so lets label that distance as x.
Now we can build a right triangle between Paul and the tree and another one between Jose and the tree as shown in the figure. Lets use cosine to find h in Paul's trianlge:
cos(59)= \frac{19}{h}
h= \frac{19}{cos(59)}
h=36.9
Now we can use the law of sines to find the distance x between Paul and Jose:
\frac{sin(43)}{36.9} = \frac{sin(16)}{x}
x= \frac{36.9sin(16)}{sin(43)}
x=14.9

Now that we know the distance between Paul and Jose, the only thing left is add that distance to the distance from Paul and the base of the tree:
19m+14.9=33.9m

We can conclude that Jose is 33.9m from the base of the tree.
