Answer:
Step-by-step explanation:
<h3>Given</h3>
- d = 2.5 ft
- Distance = 1250 ft
<h3>To find</h3>
<h3>Solution</h3>
<u>Circumference of the wheel is the one full rotation:</u>
- C = πd = 3.14*2.5 = 7.85 ft
<u>Number rotations:</u>
<u>Correct option is</u> 159 times
For 1.
Solution,
Sides(l)= 3.5
Now,
Perimeter of square=4l
=4*3.5
=14
Then,
Area of square =l^2
=3.5*3.5
=12.25
For 2.
Solution,
Sides(l)=1
Now, perimeter of square =4l
=4*1
=4
Then,
Area of square =l^2
=1*1
=1
For 3.
Solution,
Sides(l)= 20
Now,
Perimeter of square=4l
=4*20
=80
Then,
Area of square =l^2
=20*20
=400
180 is the sum of the angles, so x+3x+2x = 180
so, 6x=180
and you divide 180 by 6 which is 30
therefore x is 30
the question is asking you for angle C though which is 2x
so u do 2 times 30, which is 60 degrees
1. plot the points in the coordinate axis. Check the picture.
2. The circumcenter of a triangle is the center of the circumscribed triangle.
3. To find the circumcenter we draw the perpendicular bisector of each side, that is the line segments which are perpendicular to the sides, and divide each ith them in 2 equal parts.
4. Since all 3 perpendicular bisectors meet at the circumcenter, it is enough to draw 2 of them, as shown in the picture.
5. with our construction, we find the center O(4, 3)
Another way to solve this problem is to notice than the triangle is a right triangle. The circumcircle of a right triangle has the hypotenuse as a diameter. So it is enough to find the midpoint of FE.
