Answer:
Two semi circles would equal one circle.
The perimeter of a circle is PI x diameter.
The diameter of the circle is shown as 56 m
The perimeter of the 2 ends = 56 x 3.14 = 175.84
The length of the inside of the track is given as 130 m, and there are 2 sides so 130 + 130 = 260 m.
Total perimeter = 260 + 175.84 = 435.84 m.
Step-by-step explanation:
2.
24^2 -7^2
=576 + 49
=625
square root 625 = 25
answer is A. 25 ft (first choice)
3.
13^2 - 5^2
= 169-25
=144
square root 144 = 12
answer is d. 12 yd (last choice)

Answer:
x° = 61°
Step-by-step explanation:
Both of the "unknown" angles in the triangle are equal, since their opposite sides have equal lengths. (The triangle is isosceles.) The sum of angles in a triangle is 180°, so we have ...
58° + x° + x° = 180°
2x° = 122° . . . . subtract 58°, collect terms
x° = 61° . . . . . . . divide by 2
Answer:
324 ft
Step-by-step explanation:
1. We know there are 3 points (A, B, and C)
so far. We also know B is in the middle of A and C.
A----B----C
2. Reading further, post B is 2x as far from C as it is from A.
A----B----.----C
3. Now we know the numeral measurements of the entire stretch going from A to C (486ft).
A----B----.----C
<- 486ft ->
4. How far is point B from C??? Using the info we have, we need to break the total(486) into 3 parts.
A----B----.----C
1 2 3
5. When we divide or break 486 into 3, we get 162 ft. So each of those 3 dividing sections between A B and C are 162ft.
A----B----.----C
162 162 162
6. We know that the dividing section between B and C is double the dividing section between A and B. So, to conclude, you double 162 = 324.
7. Make sure to put it into the correct form to answer (ft) and there you go!
