Answer:
44 cm
Step-by-step explanation:
Half of the diameter is the radius so half 88 to get 44 since 88 is the diameter.
They could look at the length of the book and the size of the font to estimate the length of a book.
![V=\pi r^2 h](https://tex.z-dn.net/?f=V%3D%5Cpi%20r%5E2%20h)
r - radius, h - height
The diameter is twice the radius.
![d=12 \ m \\ r=\frac{12}{2} \ m = 6 \ m \\ h=7 \ m \\ \\ V=\pi \times 6^2 \times 7=\pi \times 36 \times 7=252 \pi \approx 252 \times 3.14=791.28 \approx 791.3](https://tex.z-dn.net/?f=d%3D12%20%5C%20m%20%5C%5C%0Ar%3D%5Cfrac%7B12%7D%7B2%7D%20%5C%20m%20%3D%206%20%5C%20m%20%5C%5C%0Ah%3D7%20%5C%20m%20%5C%5C%20%5C%5C%0AV%3D%5Cpi%20%5Ctimes%206%5E2%20%5Ctimes%207%3D%5Cpi%20%5Ctimes%2036%20%5Ctimes%207%3D252%20%5Cpi%20%5Capprox%20252%20%5Ctimes%203.14%3D791.28%20%5Capprox%20791.3)
The answer is c. 791.3 m³.
