The radius is found from

... A = πr²

... r = √(A/π) = √(154/π) m ≈ 7.00 m

The circumference is then

... C = 2πr = 2π(7.00 m) ≈ 43.99 m

The circumference is about 44.0 m.

Melanie:

$A=P(1+\frac{r}{n})^(20)\\ A=9800(1+\frac{.045}{4})^(20)\\A=$12,257.36$

Amelia:

$A=Pe^(rt)\\A=9800e^(.0475*20)\\A=$25,339.95$

Amelia-Melanie= $13,082.60
