Answer:
1256 inches
Step-by-step explanation:
The circumference of a circle is denoted by the formula: C = πd, where d is the diameter.
Here, the diameter is 400 inches, so plug that in:
C = πd
C = 3.14 * 400 = 1256
The answer is 1256 inches.
Answer:
The lines are parallel
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
Remember that
If two lines are parallel, then their slopes are the same
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
step 1
Find the slope JK
we have

substitute the values
step 2
Find the slope LM
we have

substitute the values
step 3
Compare the slopes
so
therefore
The lines are parallel
Both the numerator and the denominator can be divided by 5 to simplify the fraction:

The answer is 1/27.
Answer:
A. width = x - 4.5
B. 111 = 2(x + (x -4.5))
Step-by-step explanation:
A. The width is 4.5 meters shorter than x, so is x -4.5.
__
B. The perimeter is twice the sum of length and width. It is 111 meters, so an equation for it could be ...
111 = 2(x + (x -4.5))
