Step-by-step explanation:
Answer:
14130 yd^3
Step-by-step explanation:
The volume of a sphere is
V = 4/3 pi r^3
The diameter is 30 so the radius is d/2 = 30/2 = 15
V = 4/3 pi (15)^3
V = 4500 pi
Letting pi = 3.14
V = 14130 yd^3
Answer:
I believe that it is a irrational number.
Step-by-step explanation:
An irrational number is a number that cannot be written as a fraction with a num and denom that aren't equal to 0. These cannot be expressed as repeating decimals. -pi has all these traits, therefore it's irrational.
Answer:
B
Step-by-step explanation:
B. The independent variable is d.
Answer:
b = 6 or b = -6 (non-zero vectors)
b = 0 (zero vector)
Step-by-step explanation:
Two vectors 
and 
are orthogonal if their dot product is equal to 0, or in other words
In your case,
Hence, if vectors a and b are orthogonal, then
Note, then if b = 0, then 
and zero-vector is orthogonal to any other vectors.
Thus, b = 6 or b = -6.
