Answer:
I am so not good at math at all
86921 = 80000 + 6000 + 900 +20 +1
I think what you meant here is that the limestone is in a shape of a square pyramid. Knowing the shape, we must also know the formula for its volume:
V=s²h/3, where
s is the side of the square base
h is the vertical height of the pyramid
First, you find the area of the base s² from the known volume of the larger pyramid.
16,000 = s²(30)/3
s² = 1,600
Then, assuming both pyramids have equal areas of bases, we can use this value for the smaller pyramid. We can determine its volume to be
V = (1,600)(24)/3 = 12,800
Thus, the scale factor for the small pyramid to the big pyramid is 12,800/16,000 or 4/5.

The volume within the spherical compression wave increasing in t = 4 seconds is:64000000π cubic ft/sec.
<h3>
Volume of a sphere</h3>
Given:
dr/dt=100 ft/sec
When: t=4 seconds, radius(r)=400ft
Hence:
Volume of a sphere (V)=4/3πr³
dv/dt=4/3π.3r² dr/dt
dv/dt=4πr²dt/dr
When t=4 seconds
dv/dt=4π×(100×4)²×100 cubic ft/sec
dv/dt=4π×(400)²×100 cubic ft/sec
dv/dt=64000000π cubic ft/sec
Therefore the volume within the spherical compression wave increasing in t = 4 seconds is:64000000π cubic ft/sec.
