Answer:
A/B = 0.125
Step-by-step explanation:
Givens
r for Sphere A = 4
r for Sphere B = 8
Solution
Volume A = 4/3 pi r^3
r = 4
Volume A = 4/3 pi 4^3
Volume A = 4/3 pi 64
Note: there is no point in expanding the result. 4/3 and pi are going to cancel out when you set up the volume formula
Volume B = 4/3 pi * r^3
r = 8
Volume B = 4/3 pi * 8^3
Volume B = 4/3 pi * 512
Ratio A to B = 4/3 pi * 64 / 4/3 * pi * 512 Cancel 4/3 pi
Ratio A to B = 64/512
Ratio A to B = 1/8
Ratio A to B = 0.125
Answer:
D (north, .51)
Step-by-step explanation:
since the numbers are higher for north, it is the right answer.
.6*.85=.51
Outlier is the correct answer
Answer:
Step-by-step explanation:
20in * 20in = 400in sq
400in sq * 5 sides = 2,000in sq needed.
4in * 4in = 16in sq
Take the 2,000in sq needed and divid it by the 16in each tile covers.
2,000 / 16 = 125 tiles
Therefore, you would need 125 tiles to cover 5 sides of the table. Top and four sides.
The answer is 400 because its the "hundreds" place. Hoped this helped.
