Answer:
6.3
Step-by-step explanation:
Arc length is circumference
C = 2 * pi *r
We are finding a fraction of the total arc length
A circle is 360 degrees
45 degrees / 360 degrees = 1/8
Find the total arc length and multiply by the fraction of the circle
arc length = 2 * pi * r * 1/8
= 2 * 3.14 * 8 * 1/8
=6.28
Rounding to the nearest tenth

Hello from MrBillDoesMath!
Answer:
l = 12 feet, w = 5.5
Discussion:
Let w be the width of the pen and "l" the length. From the problem statement
l = w + 6.5 and the perimeter, P, of the fence -= 35.
Now the perimeter of the rectangle is given by the formula
P = 2l + 2w.
In our case, P = 35 and l = w + 6.5 so the equation becomes:
35 = 2(w+6.5) + 2w =>
35 = 2w + 13 + 2w =>
35 = 4w + 13 => (subtract 13 from both sides)
35-13 = 4w =>
22 = 4w =>
w = 22/4 = 5.5 feet
As, l = w + 6.5, l = 5.5 + 6.5 = 12 feet
Thank you,

Answer:
Step-by-step explanation:
The three inside angles of a triangle need to equal 180 degrees.
To find X subtract the two known angles from 180.
X = 180 - 45 - 70
X = 65 degrees.
