Answer:
12,566 ft ≈ 2.38 miles
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = πd
For a diameter of 4000 ft, the circumference of a circular crater is about ...
C = (4000 ft)(3.141593) ≈ 12,566 ft
At 5280 ft per mile, that distance is about ...
(12,566 ft)/(5280 ft/mi) ≈ 2.38 mi
The distance around the crater is about 12,566 ft or 2.38 miles.
Answer:
Step-by-step explanation:
number of side = n =7
Sum of all the angles of given polygon = (n -2)*180 = 5 *180 = 900
x + 140 +133 +145 + 117 + 119 + 125 = 900
x + 779 = 900
x = 900 - 779
x = 121

Answer:
6 Chickens
Step-by-step explanation:
Let H represent the number of horses and C represent the number of chickens. Since there are 32 legs altogether this means that on equation to use would be given by:
2C + 4 H = 32 (Eq. 1)
Another equation can be made from the fact that there are 11 heads or 11 animals altogether which can be written as:
C + H = 11 (Eq. 2)
From Eq. 2, solve for the number of chickens:
C + H = 11
C = 11 - H (Eq. 3)
Substituting Eq. 3 in Eq. 1, the number of horses can be determined:
2 C + 4 H = 32
2 ( 11 − H ) + 4 H = 32
22 − 2 H + 4 H = 32
2H = 32 − 22
2 H = 10
H = 5 Eq.4
Putting Eq.4 in Eq.1
2C + 4*5 = 32
2C = 32 - 20
2C = 12
C = 12/2
C = 6
