Find the volume of the figure. Round your answers to the nearest hundredth, if necessary. Leave your answer in terms of r.
A sphere with a diameter of 10 mi.

i think it might be a but you might want a second opinion

she will travel a distance in the range of 3 - 11 miles

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
