Since it is a square that means each side is equal.
The perimeter is 24, and since there is four sides we would divide it by four to find the length of each side.
24/4 = 6
Each side is 6.
By looking at the picture, one side of the square, is the length of the radius.
The radius of the square is 6.
The only thing left to do is to find the circumference.
The circumference formulas are:
C =

d
C = 2

r
We can use the first one Diameter x pi (3.14)
To find the diameter we would just multiply the radius by two.
6 x 2 = 12
Diameter = 12
So multiply it by pi
12 x 3.14 = 37.68
or D 12
What pool? Any of these answers work when we don’t know what pool...
No it is the right question
Answer:
Step-by-step explanation:
<h3>Part i</h3>
<u>Jennifer's account:</u>
<u>William's account can be expressed as:</u>
Because the rate of change is 14 and y-intercept is 30
<u>They will be same after x years, f(x) = g(x)</u>
- 10x + 50 = 14x + 30
- 14x - 10x = 50 - 30
- 4x = 20
- x = 5
The accounts will be same after 5 weeks
<h3>Part ii</h3>
<u>The amount in the accounts after 5 weeks:</u>
- f(5) = g(5) = 10*5 + 50 = $100
B is correct since there is one output for every input !!
have a great day :))
