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.

Answer:

Step-by-step explanation:
The way I like to think about it, with absolute value meaning the distance is
"find which number are 16 apart from 12". Which means 28 (to the right) or -4 (to the left).
More formally, applying the definition of absolute value,

So the first thing you're gonna wanna know is how many miles Brian is riding per day so
16/2= 8
Then you'll want to do the following steps
16 × 5 = 80
8 × 5 = 40
80-40 = 40
Sandi rode 40 more miles then Brian in five days
Hope this helped!
