\displaystyle\int_{x=0}^{x=4}\int_{y=x}^{y=2x}\int_{z=0}^{z=y}2xyz\,\mathrm dz\,\mathrm dy\,\mathrm dx

2xy\displaystyle\int_0^yz\,\mathrm dz=2xy\left[\frac{z^2}2\right]\bigg|_{z=0}^{z=y}=xy^3

x\displaystyle\int_x^{2x}y^3\,\mathrm dy=\frac{15}4x^5

\displaystyle\frac{15}4\int_0^4x^5\,\mathrm dx=\dfrac{15}{24}4^6=2560

Answer:

  12,566 ft ≈ 2.38 miles

Step-by-step explanation:

The circumference of a circle is given by the formula ...

  C = πd

For a diameter of 4000 ft, the circumference of a circular crater is about ...

  C = (4000 ft)(3.141593) ≈ 12,566 ft

At 5280 ft per mile, that distance is about ...

  (12,566 ft)/(5280 ft/mi) ≈ 2.38 mi

The distance around the crater is about 12,566 ft or 2.38 miles.
