We must find the area of each cake's top.
Formula for area of a circle:
where r is the radius.
<span>small cake:
</span>Plug in 4 for r because the radius is 4. (They give us the diameter, which is 8, and the radius is half that)
A = 16π
<span>big cake:
</span>Repeat the process:
Plug in 12 for r because the radius is 12. (They give us the diameter, which is 24, and the radius is half that)
A = 144π
So our two radii are 144π and 16π.
The large cake's top is not 3 times the area of the small cake's.
This makes sense because you are squaring the radius, which makes the fact that the larger cake's diameter is triple the smaller cake diameter irrelevant.
Hope this helped! ^-^

Answer:
Step-by-step explanation:
Let
x -----> the number of annual visitors pass sold
we know that
To find out the number of annual visitor passes sold, divide the total amount raised by the cost of a pass.
so
The linear equation that represent this problem is
Solve for x
Divide by 12.50 both sides
