√-80 can be factored out, to see which factors can be square rooted. A pair of factors would be 16 and -5, so that would be 4√-5. But, negative numbers cannot be inside a square root. So, √-1 is the same thing as <em>i</em>, or <u>imaginary number</u>. So, the expression equivalent to √-80 is 4<em>i</em>√5.

Answer:
C
Step-by-step explanation:
A= πr squared
D=r*2
r=24
π=3.14
A= π(24 * 24) = 576
A= π576
A=10808.64
A=10808.6
"Perimeter" means the distance all around the figure.
So it's the sum of the lengths of all the sides.
Here are a few possibilities with Perimeter = 6 units:
-- a square, with every side 1.5 units long
-- a triangle, with every side 2 units long
-- a pentagon, with every side 1.2 units long.
-- a hexagon, with every side 1 unit long.
The sides don't all need to be the same length;
they just have to all add up to 6 units.
-- another triangle, with sides 1 unit, 2 units, and 3 units long.
