4800 / 25= 192
answer: $192
Answer:
v=2πrh
r=d/2=8/2=4
Therefore, V=2×3.142×4×2= 50.272 ans.
Answer: 4

Yes scale factor means ratio. The height of the smaller pyramid to the larger pyramid in ratio form is 8:24 which simplifies to 1:3. The ratio of its areas is the scale factor squared, so 1^2:3^2=1:9. Since the surface area of the smaller pyramid is 124, the surface area of the larger pyramid must be 124x9. The ratio of volumes is the scale factor cubed, so 1^3:3^3=1:27. If the volume of the larger pyramid is 648, then the volume of the smaller pyramid is 1/27 of that, which equals 24.

3 and 375/1000
now reduce. Both are divisible by 25.
3 15/40
oops, not done yet... we can still divide by 5
3 3/8
Done!
