Answer:
The answer simplify is 16384
Step-by-step explanation:
Arc length has a formula that is similar to arc measure, but arc length is expressed in inches or meters or miles, etc., whereas measure is expressed in degrees, like an angle. The formula for each take this into account. Since the arc length is part of the length of the outside of the circle, the formula includes the circumference for a circle.

, where theta is the degree measure of the central angle intersecting the arc you're looking for, and d is the diameter of the circle. Our formula would look like this with the info we have:

which can be simplified to

which can be simplified even further to

. And that's your answer!
26 to nearest year
We require the total of the sums of ages for both groups before calculating the mean for all 16
using mean = 
Women
27 =
( cross- multiply )
sum = 9 × 27 = 243
Men
25 =
( cross- multiply )
sum = 7 × 25 = 175
Total sum of all 16 = 243 + 175 = 418
mean =
= 26 ( to nearest year )
Answer: 769.3
Step-by-step explanation:

C=2*3.14*122.5
245/2=122.5
C=769.3
The perimeter of a rectangle, is all of the sides added up.
In a rectangle, there are two widths (right and left), and two lengths (up and down)
So:
Perimeter = 2 × width + 2 × length.
To get the equation we just substitute in the values that we are given:
length = (x)
width = (x - 4)
perimeter = 87
So just put these values into: perimeter = 2 × width + 2 × length:
87 = 2(x) + 2(x - 4)
_____________________________
Answer:
The equation is: 87 = 2(x) + 2(x - 4)
<em>(note: this can be simplified down like so:</em>
<em>87 = 2x + 2x - 8</em>
<em>87 = 4x - 8</em>
<em>95 = 4x</em>
23.75 = x
