Answer:

25 pages

Step-by-step explanation:

Create a proportion:

$\frac{pages}{minutes}$ = $\frac{20}{60}$ = $\frac{x}{75}$

LuckyWell [14K]

To best estimate the volume of the log, we assume that the diameter is the average of the diameters at both ends giving us 12 inches as the diameter. Thus, the radius is equal to 0.5 ft. The volume of the log is calculated through the equation,
V = πr²h = π(0.5 ft)²(10 ft) = 7.85 ft³
