Answer:

Step-by-step explanation:
a hemisphere is half a sphere.
And if the formula for the volume of a sphere is:

we must calculate the volume of the sphere and in the end divide by two to find the volume of the hemisphere.
Since the radius is:

substituting this into the formula for volume:

this is the volume of the total sphere, thus the volume of a hemisphere is:

rounding to the nearest tenth:

The equation would be:
3.50 + 0.15x
x represents each 'late day'
5/6 = 0.833333 .... (non-terminating)
41.8 because u just move one over
145 pages because 145 would round up to 150 but anything below 145 would round to 140
