Answer:
It would be option 2.
Step-by-step explanation:
This is because option 1 does not have a irrational number that goes on indefinitely, option three has the square root of 25, which equals 5 meaning it is rational, and the last option also gives us rational choices. Therefore, the only possibility is that it would be option 2.

Answer:
B. 50 times greater
Step-by-step explanation:
Given;
size of phytoplankton = 2 × 10⁻⁶ in
size of sand grain = 1 × 10⁻⁴ in
Determine how many times longer the grain of sand is than the phytoplankton.
Divide the sand size by the phytoplankton size, to find out how much greater the sand is.
This can be done by equating it as follows;
2 × 10⁻⁶ (y) = 1 × 10⁻⁴

Therefore, the grain of sand is 50 times greater than the phytoplankton
B. 50 times greater
Answer:
263.76 m^3
Step-by-step explanation:
Using 3.14 as pi
pi * radius^2 * height / 3
3.14 * 6^2 * 7 / 3
3.14 * 36 * 7 /3
3.14 * 252 /3
3.14 * 84
263.76
