Answer:
B
Step-by-step explanation:
The volume of a rectangular prism is the length times width times height.
V = LWH
V = (4√3)(3√6)W
V = 12√18 W
V = 36√2 W
If the volume is irrational, then W cannot have a radical that is half of a perfect square, because when multiplied by √2, that would yield a rational volume. For example, √18 × √2 = √36 = 6.
Therefore, the answer must be B, because 12 is not half of a perfect square.
V = 36√2 (4√12)
V = 144√24
V = 288√6
Answer: the 2nd one
Step-by-step explanation: because i said so ur the dum one
Answer:
D. 13
Step-by-step explanation:
You can do the product in the straight-forward way ...
... (3 -2i)(3 +2i) = 3·3 +3·2i -3i·3 -(2i)(2i)
... = 9 +6i -6i -4i² . . . . . note the middle two terms cancel
Recognize that i = √-1, so i² = -1. Then the sum is
... = 9 -4(-1) = 9+4 = 13

Answer

Explanation
The formula to determine the area of a circle is 
Convert the diameter to radius
30/2 = 15
The radius is 15
Plug in the radius into the formula above

225 *
= approximately
