<h3>
Answer: B) Complex numbers</h3>
Complex numbers are always in the form a+bi with 'a' and 'b' as real numbers.
If b = 0 and 'a' is nonzero, then a+bi = a+0i = a which is strictly a real number
If a = 0 and b is nonzero, then a+bi = 0+bi = bi indicating that the number is now purely imaginary
It'd be 9.096491 hope that helps.
Answer:
1130.97336 units^3
Step-by-step explanation:
The volume of a cylinder can be found using:

We have the area of the base, but not the radius

We know the area is
, so we can substitute that in for a

We want to find r, so we need to isolate it
Divide both sides by pi
36=r^2
Take the square root of both sides
6=r
Now we know the radius, and can substitute it into the volume formula, and we can substitute the height (10) in


Solve the exponent


v=1130.97336
The volume is 1130.97336 units^3
