Answer:

82.1

Step-by-step explanation:

So the circumference of the whole circle is 46π.

A quarter of that is 11.5π.

11.5π ≈ 36.1283155163

Simplify that to 1 decimal point: 36.1

Then you add 46 to that.

36.1 + 46 = 82.1

Answer:

$7,987.64

Step-by-step explanation:

We know,

A = Pe^(rt)

Here,

A = 11000

interest r = .08

Time t = 4

Now,

11000 = Pe^(.08 * 4)

Or, 11000 = Pe^.32

Or, 11000 / e^.32 = P

Or, 7987.6394 = P

Or, P= 7,987.64

Jerome will have to ask for $7,987.64 to his parents.
